Fast pyrolysis of biomass for bio-oil production is a direct route to renewable liquid fuels, but raw bio-oil must be upgraded in order to remove easily polymerized compounds (such as phenols and furfurals). Herein, a synthesis strategy for graphene encapsulated Ru nanoparticles (NPs) on carbon sheets (denoted as Ru@G-CS) and their excellent performance for the upgrading of raw bio-oil were reported. Ru@G-CS composites were prepared via the direct pyrolysis of mixed glucose, melamine and RuCl3 at varied temperatures (500-800 C). Characterization indicated that very fine Ru NPs (2.5 ± 1.0 nm) that were encapsulated within 1-2 layered N-doped graphene were fabricated on N-doped carbon sheets (CS) in Ru@G-CS-700 (pyrolysis at 700 C). And the Ru@G-CS-700 composite was highly active and stable for hydrogenation of unstable components in bio-oil (31 samples including phenols, furfurals and aromatics) even in aqueous media under mild conditions. This work provides a new protocol to the utilization of biomass, especially for the upgrading of bio-oil.

Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. In an article, author is Gicquiaud, Julien, once mentioned the application of 145-42-6, Name is Monosodium taurocholate, molecular formula is C26H44NNaO7S, molecular weight is 537.69, MDL number is MFCD00150819, category is chiral-catalyst. Now introduce a scientific discovery about this category, COA of Formula: C26H44NNaO7S.

The first example of an enantioselective carbocyclization of an alkyne-containing substrate catalyzed by chiral Bronsted acids was achieved. The use of the 2-hydroxynaphthyl substituent on the alkyne as a directing group constituted the key parameter enabling both efficient regioselective protonation of the carbon-carbon triple bond and chiral induction. The key cationic intermediate could be depicted either as a cationic vinylidene ortho-quinone methide or a stabilized vinyl cation. Atropoisomeric phenanthrenes derivatives were produced in high yields and good enantioselectivities under mild, metal-free reaction conditions in the presence of chiral N-triflylphosphoramide catalysts. The carbenic nature of the cationic intermediate was also exploited to describe an example of alkyne/alkane cycloisomerization.

The catalytic asymmetric hydrogenation of prochiral olefins is one of the most widely studied and utilized transformations in asymmetric synthesis. This straightforward, atom economical, inherently direct and sustainable strategy induces chirality in a broad range of substrates and is widely relevant for both industrial applications and academic research. In addition, the asymmetric hydrogenation of enamides has been widely used for the synthesis of chiral amines and their derivatives. In this review, we summarize the recent work in this field, focusing on the development of new catalytic systems and on the extension of these asymmetric reductions to new classes of enamides. 1 Introduction 2 Asymmetric Hydrogenation of Trisubstituted Enamides 2.1 Ruthenium Catalysts 2.2 Rhodium Catalysts 2.3 Iridium Catalysts 2.4 Nickel Catalysts 2.5 Cobalt Catalysts 3 Asymmetric Hydrogenation of Tetrasubstituted Enamides 3.1 Ruthenium Catalysts 3.2 Rhodium Catalysts 3.3 Nickel Catalysts 4 Asymmetric Hydrogenation of Terminal Enamides 4.1 Rhodium Catalysts 4.2 Cobalt Catalysts 5 Rhodium-Catalyzed Asymmetric Hydrogenation of Miscellaneous Enamides 6 Conclusions

Enantiopure beta-nitroalcohols are versatile intermediates used in the synthesis of important pharmaceuticals and chiral synthons. In this article, immobilizedArabidopsis thalianaHNL (AtHNL)-catalyzed preparation of (S)-beta-nitroalcohols from their racemic mixtures via retro-Henry reaction was studied.AtHNL used in biocatalysis was immobilized by physical adsorption in inexpensive celite (R) 545. Under optimized biocatalytic conditions, the total turnover number of the catalyst has improved 2.3-fold for (S)-2-nitro-1-phenylethanol (NPE) synthesis, than free enzyme catalysis. This study reported for the first time celite-AtHNL-catalyzed retro-Henry reaction at low pH. At pH 4.5 and 5.0, 62% ee and 41% conversion, and 97% ee and 42% conversion of (S)-NPE were obtained respectively, while the free enzyme inactivates at pH < 5.0. The increased catalytic efficiency and pH stability of the catalyst could be possibly due to increased stability ofAtHNL by immobilization. A dozen of racemic beta-nitroalcohols were converted into their corresponding (S)-beta-nitroalcohols using this reaction; among them, eight were not tested earlier. The immobilized enzyme has showed broad substrate selectivity in the retro-Henry reaction, and products were obtained up to 98.5% ee. Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 145-42-6, in my other articles.
