Ribeiro, Adriana Santos published the artcileSynthesis of (R)-(-) and (S)-(+)-3-(1-pyrrolyl)propyl N-(3,5-dinitrobenzoyl)-α-phenylglycinate and derivatives. A suitable chiral polymeric phase precursor, Application of 3-(1H-Pyrrol-1-yl)propan-1-ol, the main research area is phenylglycine N dinitrobenzoyl derivative enantiomeric preparation; pyrrolylpropyl dinitrobenzoylphenylglycinate preparation precursor polymeric film.

A synthetic route to obtain 3-(1-pyrrolyl)propyl (R)- and (S)-N-(3,5-dinitrobenzoyl)-α-phenylglycinate (1, 2) and derivatives is described. In a first step, pyrrole derivatives were prepared using the Clauson-Kaas method. The esterification, second step, was performed using basic conditions due to sensitivity of the pyrrole group toward acidic conditions. A tautomeric equilibrium involving the stereogenic center induces the product epimerization. The substitution of DMAP and Et3N by a highly hindered base, proton-sponge, furnished the final products without racemization. The enantiomeric excess of 1, 2 and of the corresponding Me esters (3 and 4) were determined by 1H NMR anal. in the presence of optically active Eu(tfc)3. Epimerization was not observed in the preparation of the amine salts of (R)- and (S)-N-(3,5-dinitrobenzoyl)-α-phenylglycine with triethylamine and 1-[3-(dimethylamino)propyl]pyrrole.

Yasuzawa, Mikito published the artcileCharacterization of N-substituted polypyrrole thin-film electrode having immobilized glucose oxidase, SDS of cas: 50966-69-3, the main research area is polypyrrole electrode glucose oxidase.

The authors describe the properties of a glucose sensor prepared by the electropolymerization or pyrrole derivatives, 1-pyrrole propionic acid (PPA) and 1-pyrrole propanol (PPO), which have a carboxyl group and hydroxyl group, resp. Since these derivatives have substituents that can possibly make a hydrogen bond with GO, these electrodes are expected to afford higher electrode stability and reproducibility compared with that of unsubstituted pyrrole.

Carpio, Humberto published the artcileSynthesis of 1,2-dihydro-3H-pyrrolo[1,2-a]pyrrole-1-carboxylic acids and homologous pyridine and azepine analogs thereof, Synthetic Route of 50966-69-3, the main research area is pyrrolopyrrolecarboxylic acid; pyrrolopyridinecarboxylic acid; pyrroloazepinecarboxylic acid; pyrroleacetate; pyridinecarboxylic acid pyrrolo; azepinecarboxylic acid pyrrolo.

Several syntheses of the previously unknown 1,2-dihydro-3H-pyrrolo[1,2-a]pyrrole-1-carboxylic acid (I) and various 5- and 6-substituted derivatives were devised. Some of these processes were extended to the heretofore unreported 5,6,7,8-tetrahydropyrrolo[1,2-a]pyridine-8-carboxylic acid (II) and 5,6,7,8-tetrahydro-9H-pyrrolo[1,2-a]azepine-9-carboxylic acid derivatives (e.g., III). Two new processes were developed for the conversion of pyrroles into the corresponding pyrrole-2-acetic acid esters. Both processes were based on the use of the readily available ethoxalylpyrrole derivatives as the starting material. One sequence involved saponification of the α-keto ester, followed by Wolff-Kishner reduction of the crude α-keto acid salt and subsequent esterification of the acetic acid derivative thus produced. The 2nd synthesis commenced with reduction of the 2-ethoxalpyrrole with NaBH4 to the α-hydroxy ester, which was further reduced to the acetic acid ester with an equimolar mixture of PPh3 and PPh3I2.

Baltes, W. published the artcileModel reactions on roast aroma formation – the reaction of serine and threonine with sucrose, Computed Properties of 50966-69-3, the main research area is coffee aroma formation model reaction; sucrose reaction serine threonine aroma; serine reaction sucrose coffee aroma; threonine reaction sucrose coffee aroma; Maillard reaction coffee aroma.

About 350 compounds were identified in the mixture obtained by reacting serine and threonine with sucrose under conditions of coffee roasting (220°). More than 120 pyrazines were found. In the presence of excess sucrose, the concentration of pyrazines amounted to 22% from the reaction with threonine and 5% from that with serine, whereas when serine and threonine were heated with little or no sucrose, pyrazine concentrations reached 32-38% of total volatiles. Volatiles also contained >70 pyrroles, 2 dihydropyrrolizines, alkylated pyridines (from Maillard reaction and pyrolysis of hydroxy amino acids), and, in the presence of sugar, acetylpyrines. With excess sucrose, 57-62% of the products were furan derivatives Raw Arabica coffee was reacted in the same tube used for the model mixtures By comparison of the results, 53 volatiles not previously described in coffee aroma were found, including 7 pyridines, 12 alkyl- or alkenyl pyrazines, 3 pyrrolopyrazines, 1 furfuranylpyrazine, and N-pyrrolylethanol  [6719-02-4].

Kutzki, Olaf published the artcileSynthesis and properties of novel porphine-fullerene dyads for the investigation of light induced energy and electron transfer, Application In Synthesis of 50966-69-3, the main research area is fullerene porphyrin chlorin dyad preparation luminescence quenching; transition metal porphyrin chlorin fullerene preparation luminescence; copper pyrrolylpropyl deuteroporphyrin IX preparation; cobalt phosphonopropylporphyrin preparation; zinc porphyrin chlorin fullerene dyad preparation luminescence quenching.

A variety of dyads and more complex mol. arrangements of donor and acceptor subunits were designed to investigate light induced energy and electron transfer to mimic natural photosynthesis. Since the discovery and availability of the fullerenes, especially fullerene C60 was used as a subunit for the construction of mol. dyads which undergo light induced electron transfer from a porphinoid donor to the fullerene acceptor. A possible advantage of fullerenes over quinones, which were used as acceptors by nature and in the majority of artificial photosynthetic systems, is the ability of C60 to accept up to six electrons, and is the lower reorganization energy of C60 compared to quinones according to Marcus theory.

Allcock, Harry R. published the artcilePolyphosphazenes bearing polymerizable pyrrole, thiophene, and furan side groups: synthesis and chemical oxidation, HPLC of Formula: 50966-69-3, the main research area is polyphosphazene preparation polymerizable heterocycle containing; furan containing polyphosphazene preparation doping; pyrrole containing polyphosphazene preparation doping; thiophene containing polyphosphazene preparation doping; doping polyphosphazene polymerizable heterocycle containing; conductivity heterocycle containing polyphosphazene.

Several polyorganophosphazenes containing polymerizable, heterocyclic side groups, (e.g., furan, thiophene, and pyrrole derivatives) were prepared by reaction of polydichlorophosphazenes with the Na salt of the corresponding hetercyclic alkoxide. The prepared polyphosphazines were doped with Fe(ClO4)3, FeCl3, or I to give semi-conductive polymers, and the conductivity is discussed with respect to polymerization of the heterocycle within the polymer. The prepared polymers were characterized by NMR spectroscopy, gel permeation chromatog., elemental microanal., and DSC. Possible explanations for the relatively low conductivity of the polymers are discussed, including interchain hopping distances, insolubility of the crosslinked polymers, and immobilization of the heterocyclic side groups. The last 2 factors may serve to minimize heterocyclic polymer chain growth, thereby keeping the resultant conductivity low.

Copolymers derived from mixtures of pyrrole and N-(hydroxypropyl)pyrrole have been prepared electrochem. using various concentration ratios. Copolymers were generated on stainless electrodes by chronoamperometry and cyclic voltammetry in a LiClO4 acetonitrile solution Relevant phys. (d. and doping level) and electrochem. (electroactivity and electrostability) properties of the copolymers have been examined and compared with those of the two corresponding homopolymers, which were prepared using the same electrochem. procedures. Results show that the copolymer obtained using the 25:75 N-(hydroxypropyl)pyrrole:pyrrole molar ratio presents an interesting behavior. Finally, the ability of the latter copolymer to form specific interactions with plasmid DNA has been compared with that of polypyrrole.

Trombach, N. published the artcileSynthesis and electropolymerization of pyrrol-1-yl substituted phthalocyanines, HPLC of Formula: 50966-69-3, the main research area is pyrrolyl alkoxy phthalocyanine monomer preparation cyclotrimerization substitution; polypyrrole phthalocyanine preparation oxidative polymerization isolated electroactive group; redox potential electrochromism polypyrrole phthalocyanine conducting polymer.

Metal-free and Zn, Co, Ni – 2,9,16,23-Tetrakis(2-pyrrol-1-yl-alkoxy)phthalocyanines, in which the phthalocyanine is connected via an alkylene spacer to a pyrrole substituent, were prepared via three step reaction sequence to obtain monomers with groups for electropolymerization electronically isolated from the phthalocyanine. The synthesis sequence involves cyclotrimerization, substitution of NO2 groups with OH groups, then conversion to the phthalocyanine ring by the Li pentanolate method. Electrochem. oxidative polymerizations were carried out either under potentiodynamic conditions by scanning between 0.1 and 1.4 V vs. SCE at scan rate of 10 mV s-1 or at a fixed potential of 1.4 V vs. SCE. Polypyrrole films of thickness up to 5 μm were obtained on ITO electrodes. The UV/Vis spectra show the presence of phthalocyanine and polypyrrole structural units in the polymers. The charge-discharge redox process of the conducting polymers is accompanied by a reversible electrochromic color change. The polypyrrole-phthalocyanine films exhibit specific elec. conductivity of ∼10-5 S-cm-1.
