A reagent-controlled chemoselective process has been devised for the synthesis of 4H-1,3-benzoxazines and related biol. important heterocycles in high yields under mild conditions. These scaffolds could be efficiently constructed using two different chemoselective reactions that rely on the choice of reagents and reaction conditions. The treatment of various 2-amino-arylalkyl alcs. with isothiocyanates afforded thiourea intermediates, which were reacted in situ with mol. iodine in the presence of triethylamine to give 2-amino-4H-1,3-benzoxazines, whereas the corresponding 2-amino-4H-1,3-benzothiazines were obtained by the reaction of thiourea intermediates in the presence of T3P (a mild cyclodehydrating agent) and triethylamine as the base. The described protocol represents the first example for the synthesis of 4H-1,3-benzoxazines via the dehydrosulfurization method using mol. iodine as the reagent.

Gholinejad, Mohammad; Dasvarz, Neda; Shojafar, Mohammad; Sansano, Jose M. published the artcile< Starch functionalized creatine for stabilization of gold nanoparticles: Efficient heterogeneous catalyst for the reduction of nitroarenes>, Quality Control of 5344-90-1, the main research area is starch creatine stabilization gold nanoparticle catalyst reduction nitroarene.

Selective reduction of nitroarom. pollutants into amines with recoverable and reusable heterogeneous catalysts is highly desirable. Herein, we prepared and characterized an efficient novel catalyst comprising 4 nm size Au nanoparticles supported on creatine modified starch. Using this catalyst, efficient reduction of nitroarenes into amines at room temperature in aqueous media was achieved. The presence of creatine in the structure of the catalyst plays important role in amount of Au loading, efficiency of the catalyst, recycling times, and leaching of Au compared to starch supported Au without creatine.

Yalcinkaya, Sueleyman; Cakmak, Didem; Seymen, Kuebra; Demetguel, Cahit published the artcile< Electrochemical synthesis and characterization of poly (o-amino benzyl alcohol) and poly (o-amino benzyl alcohol-co-o-anisidine)>, Synthetic Route of 5344-90-1, the main research area is electrochem synthesis polyamino benzyl alc anisidine copolymer.

In this study; poly (o-amino benzyl alc.) and poly (o-amino benzyl alc.-co-o-anisidine) copolymer films were electrochem. synthesized by cyclic voltammetry technique on the platinum electrode. The synthesis of copolymer films was achieved in various monomers feed ratio (o-amino benzyl alc.: o-anisidine; 8:2, 1:1, 2:8) of o-amino benzyl alc. and o-anisidine. Different solution types were tested in aqueous and non-aqueous media, especially during the synthesis process, as the electrolyte medium. As a result of the experiments, it was determined that sulfuric acid solution was the most suitable solution for both homopolymer and copolymer film growth. Homopolymer and copolymer samples were characterized by FT-IR, cyclic voltammetry (CV), SEM, digital images and TGA/DTA techniques. The CV, SEM and digital images results indicated that the solution which has high ratio of monomer is more effective in copolymer film synthesis mechanism. TGA results showed that the 1:1 copolymer film had higher thermal stability than the films at other monomer ratios. Also, electrochem. studies exhibited that the copolymer film in 1:1 ratio is partially more electrochem. stable than other copolymer films.

Donthireddy, S. N. R.; Singh, Vivek Kumar; Rit, Arnab published the artcile< A heteroditopic NHC and phosphine ligand supported ruthenium(II)-complex: an effective catalyst for the N-alkylation of amides using alcohols>, Name: (2-Aminophenyl)methanol, the main research area is alkylation aromatic amide aralkyl alc ruthenium chelate carbene catalyst; ruthenium imidazolylidene triazolylidene mesoionic carbene preparation amide alkylation catalyst; secondary aromatic amide benzyl preparation alkylation arenemethanol ruthenium catalyst.

A ruthenium(II) complexes [(p-cymene)RuCl(1-MeIm-3-CH2Trz-1-C6H4R)] (Im = 2-imidazolylidene, Trz = 1,2,3-triazol-4-yl-5-ylidene; R = 2,4,6-Me3, 4-MeO, 4-CF3) supported by chelate NHC and mesoionic carbene ligands in combination with a diphosphine ligand (dppe, dppf) was shown to be a highly effective catalyst for the N-alkylation of diverse aromatic amides ArCONH2 using readily available primary aralkyl alcs. Ar1CH2OH, yielding N-benzylamides ArCONHCH2Ar1 (Ar, Ar1 = substituted Ph, pyridyl, thienyl, naphthyl). A wide range of secondary amides was thus obtained in excellent yields (up to 98%) employing a low catalyst loading of 0.2 mol% and a substoichiometric amount of base. The 1H NMR and ESI-MS analyses support the participation of a N-heterocyclic carbene and phosphine supported Ru-H species in the catalytic cycle and the mechanistic studies including the deuterium labeling experiment suggest the involvement of a borrowing hydrogen protocol. Addnl., the present catalytic system was also revealed to be efficient for the selective mono-alkylation and unsym. di-alkylation of 4-aminobenzamides which have not been studied before to the extent of our knowledge.

Two new tetranuclear zinc(II) complexes, [Zn4(L1)2(μ2-η1:η1-CH3COO)4(μ1,1-N3)2] (1) and [Zn4(L2)4(CH3CH2OH) (H2O)] (2), where L1 and L2 are the deprotonated forms of 4-fluoro-2-((pyridin-2-ylmethylimino)methyl)phenol (HL1) and 4-fluoro-2-((2-(hydroxymethyl)phenylimino)methyl)phenol (H2L2), have been synthesized and characterized by elemental anal., IR and UV-vis spectroscopy, and single crystal X-ray diffraction.

Zhong, Yuanhai; Zhou, Taigang; Zhang, Zhuohua; Chang, Ruiqing published the artcile< Copper-Catalyzed Transfer Hydrogenation of N-Heteroaromatics with an Oxazaborolidine Complex>, Category: alcohols-buliding-blocks, the main research area is quinoline hydrogenation oxaborolidine borane complex copper catalyst; tetrahydroquinoline preparation transfer hydrogenation quinoline oxaborolidine borane complex.

Quinolines, quinoxalines, acridine and 1,10-phenanthroline were hydrogenated at the heterocyclic ring by borane-oxaborolidine complex, prepared in situ from ethanolamine and BH3·THF, giving tetrahydro-derivatives; the reaction is catalyzed by copper(II) and copper(I) salts. The first time use of the oxazaborolidine complex in transfer hydrogenation, was accomplished. A general and efficient method for copper-catalyzed transfer hydrogenation of a variety N-heteroaromatics with oxazaborolidine-BH3 complex under mild reaction conditions afforded the corresponding hydrogenated products in up to 96% yields. Mechanistic studies indicate that the hydrogen source originated from water and borane that coordinate with the nitrogen atom of oxazaborolidine. Accordingly, a plausible mechanism for this reaction was proposed. This method was successfully used in the key step synthesis of natural products (±)-Angustureine and (±)-Galipinine in three steps.

The authors report a highly facile and unprecedented approach to synthesize congested N-(hetero)aryl amines, e.g., 4-NCC6H4NNHCMe2CONHOBn, en route to α-amino acid amides using α-bromoamides as alkylating agents under mild reaction conditions (room temperature). The involvement of aza-oxyallyl cations as alkylating agents is the hallmark of this reaction. This method was readily adapted for the rapid synthesis of coveted 1,4-benzodiazepine-3,5-diones I [R = R1 = H, MeO, R2 = OBn; R = R1 = R2 = H; R = R1 = MeO, R2 = H; R = H, R1 = Cl, R2 = OBn].
