Utsukihara, Takamitsu; Horiuchi, C. Akira published the artcile< Production of chiral aromatic alcohol by acetophenone and 1-arylethanol derivatives using vegetables>, Computed Properties of 403-41-8, the main research area is Ducus Solanum chiral aromatic alc acetophenone arylethanol.

We have studied the biotransformation of acetophenone derivatives (1a-1f) and 1-arylethanol derivatives (2a-2e, 2g, 2h) using various vegetables. It is found that the reduction of acetophenone derivatives (1a-1f) using carrot (Ducus carota) gives (S)-1-arylethanols with high enantioselectivity. On the other hand, biooxidation of 1-arylethanols (2a-2e, 2g, 2h) using potato (Solanum tuberosum) is oxidized to give (R)-1-arylethanols as major product with high stereoselectivity. Carrot (D. carota) is the best catalyst for this reduction and shows a good reaction yield and enantioselectivity. On the other hand, it is found that the racemic alcs. are converted into the corresponding (R)-alcs. with high ee using Japanese potato (S. tuberosum) as catalyst. The availability of the enzymic system using various vegetables is convenient and an eco-friendly system.

The present study describes the first example of synthesis of pharmaceutically relevant N-heterocycles like substituted quinolines I (R1 = Ph, 2-pyridinyl, benzo[d][1,3]dioxol-5-yl, 3-phenylpropyl, etc.; R2 = H, Me; R1R2 = -(CH2)3-; R3 = H, Cl, Br, Me; R4 = H; R3R4 = -CH=CH-CH=CH-), acridines e.g., II and 1,8-naphthyridines III in water under air using 2-aminoaryl alcs. or 2-nitroaryl alcs. 2-R5-4-R4-5-R3C6H2CH2OH (R5 = NH2, NO2) and 2-amino-3-pyridinemethanol with secondary alcs.

Muthuvinothini, A.; Stella, S. published the artcile< Surface modified nanoparticles: a green catalyst for the reduction of ketones>, Related Products of 403-41-8, the main research area is metal oxide glycerol nanoparticle green catalyst ketone reduction.

In the present study, a creative and eco-friendly synthetic method was demonstrated for the reduction of ketones using surface modified metal oxide nanoparticles (MO NPs). Nickel oxide, iron oxide and copper oxide nanoparticles were biosynthesized from the aqueous immature fruit extract of Cocos nucifera and the nanoparticle’s surface was modified using glycerol to improve the catalytic efficiency. Surface modification of the nanoparticles enhanced the catalytic activity of nanoparticles as compared to the unmodified metal oxide nanoparticles (MO NPs) for the reduction of ketones. Among the MO NPs used as catalysts for the reduction of acetophenone derivatives, glycerol modified iron oxide nanoparticles showed greater results with 74%-91% of yield due to its uniform morphol. The catalyst retained its stability even after seven repeated cycles of reaction.

Thiyagarajan, Subramanian; Gunanathan, Chidambaram published the artcile< Ruthenium-Catalyzed Selective Hydrogenation of Epoxides to Secondary Alcohols>, Reference of 403-41-8, the main research area is secondary alc preparation green chem; epoxide regioselective hydrogenation ruthenium catalyst.

A ruthenium(II)-catalyzed highly selective Markovnikov hydrogenation of terminal epoxides to secondary alcs. is reported. Diverse substitutions on the aryl ring of styrene oxides are tolerated. Benzylic, glycidyl, and aliphatic epoxides as well as diepoxides also underwent facile hydrogenation to provide secondary alcs. with exclusive selectivity. Metal-ligand cooperation-mediated ruthenium trans-dihydride formation and its reaction involving oxygen and the less substituted terminal carbon of the epoxide is envisaged for the origin of the observed selectivity.

The synthesis of rare anionic heteroleptic and homoleptic α-diimine iron complexes is described. Heteroleptic BIAN complexes [(cod)Fe(BIAN)][K([18]c-6)(thf)0.5] (1) and [(dnbe)Fe(BIAN)][K([18]c-6)(thf)2] (2; H2BIAN = N,N’-Dipp2-1,2-acenaphtylenediamine, cod = 1,5-cyclooctadiene, dnbe = 5,5′-dinorbornene-6,6′-diyl)were synthesized by reduction of the [(BIAN)FeBr2] precursor complex using stoichiometric amounts of potassium graphite in the presence of the corresponding olefin. The electronic structure of these paramagnetic species was investigated by numerous spectroscopic analyses (NMR, EPR, 57Fe Mossbauer, UV-vis), magnetic measurements (Evans NMR method, SQUID), and theor. techniques (DFT, CASSCF). Whereas anion 1 is a low-spin complex, anion 2 consists of an intermediate-spin Fe(III) center. Both complexes are efficient precatalysts for the hydroboration of carbonyl compounds under mild reaction conditions. The reaction of bis(anthracene) ferrate(1-) gave the homoleptic BIAN complex 3-[K([18]c-6)(thf)], which is less catalytically active. The electronic structure was elucidated with the same techniques as described for complexes 1-[K([18]c-6)(thf)0.5] and 2-[K([18]c-6)(thf)2] and revealed an Fe(II) species in a quartet ground state. Highly reduced ferrate anions were synthesized and structurally characterized. The mol. structures were elucidated by X-ray crystallog. Because of the presence of redox-active α-diimine ligands, the electronic situation was thoroughly analyzed using high-level quantum chem. calculations 57Fe-Mossbauer, EPR, NMR, and UV-vis spectroscopies and SQUID magnetization measurements were employed to characterize the spectroscopic and magnetic properties. Two of the new complexes prepared are precatalysts for the hydroboration of carbonyl compounds requiring low catalyst loadings.

A simple bipyridine-based Mn catalysts were developed that act as active catalysts for transfer hydrogenation of ketones, aldehydes and imines. For the first time, Mn-catalyzed transfer hydrogenation of N-heterocycles was reported. The highest catalytic activity among complexes with variously substituted ligands was observed for the complex bearing two OH groups in bipyridine. Deuterium labeling experiments suggested a monohydride pathway.

Li, Dianfeng; Wang, Jinguo; Xu, Fengxia; Zhang, Nianchen; Men, Yong published the artcile< Mesoporous (001)-TiO2 nanocrystals with tailored Ti3+ and surface oxygen vacancies for boosting photocatalytic selective conversion of aromatic alcohols>, Safety of 1-(4-Fluorophenyl)ethyl Alcohol, the main research area is mesoporous anatase catalyst morphol aromatic alc oxidation.

Selective conversion of aromatic alcs. to value-added chems. is becoming an emerging research hotspot in heterogeneous photocatalysis, but its critical challenge is how to construct highly efficient photocatalysts. Herein, mesoporous (001)-TiO2 nanocrystals with tailored Ti3+ and surface oxygen vacancies have been fabricated by a facile hydrothermal route, showing remarkably boosted photoactivity for selective conversion of aromatic alcs. to carbonyl compounds in water medium under visible-light irradiation Results attest that the remarkably boosted photoactivity was mainly correlated with the strong synergetic effect of exposed (001) facets, Ti3+ self-doping, and surface oxygen vacancies, leading to the enhanced reactant (aromatic alcs. and O2) activation via the high surface energy of (001) facets, the improved visible-light absorbance via the intrinsic band gap narrowing, and the escalated photoelectron-hole separation efficiency via Ti3+ and surface oxygen vacancies acting as electron sinks. Meanwhile, a plausible photocatalytic mechanism for selective conversion of aromatic alcs. to carbonyl compounds has been elucidated in detail based on active species identified by capture experiments It is hoped that this work can deliver some new insights into the rational design of highly efficient photocatalysts applied in future green organic selective transformation reactions.

Ma, Da Hun; Jaladi, Ashok Kumar; Lee, Ji Hye; Kim, Tae Sung; Shin, Won Kyu; Hwang, Hyonseok; An, Duk Keun published the artcile< Catalytic Hydroboration of Aldehydes, Ketones, and Alkenes Using Potassium Carbonate: A Small Key to Big Transformation>, Electric Literature of 403-41-8, the main research area is aldehyde ketone alkene hydroboration potassium carbonate catalyst.

An efficient transition-metal-free protocol for the hydroboration of aldehydes and ketones (reduction) was developed. The hydroboration of a wide range of aldehydes and ketones with pinacolborane (HBpin) under the K2CO3 catalyst was studied. The reaction system is practical and reliable and proceeds under extremely mild and operationally simple conditions. No prior preparation of the complex metal catalyst was required, and hydroboration occurred stoichiometrically. Further, the chemoselective reduction of aldehydes over ketones was carried out. Moreover, the authors demonstrated the use of K2CO3 as an efficient catalyst for the hydroboration of alkenes. The operational simplicity, inexpensive and transition-metal-free catalyst, and the applicability to gram-scale synthesis strengthen its potential applications for hydroboration (reduction) at an industrial scale.
