METHOD FOR PRODUCING ESTER CONDENSED PRODUCT

The present invention is to provide a method for preparing an ester condensate and a catalyst therefor; wherein the method enables synthesis of enormous amounts of ester condensates comprising a specific structure in good yield, by a reaction of carboxylic acid and alcohol in equimolar amounts, while generation of by-products is prevented; wherein the catalyst exhibits good catalytic efficiency as a catalyst for use, the use of the catalyst in small amount is sufficient, and the catalyst is reusable and can be used repeatedly; therefore, the method for preparing an ester condensate of the present invention and the catalyst therefor can be applied to industrial methods which are preferable in view of green chemistry. Esterification reaction is performed by using a catalyst comprising a zirconium(IV) compound and/or a hafnium(IV) compound and an iron compound and a gallium compound. It is preferable that the zirconium(IV) compound is a compound represented by Zr(OH)a(OR1)b, (wherein, R1 represents an acyl group or an alkyl group, and each of a and b is 0 or any one of integers of 1 to 4 and the relationship of a + b = 4 is satisfied), and a zirconium(IV) halide.

Synthesis of C-Nucleosides via Radical Coupling Reaction

Photolysis of O-acyl derivatives of N-hydroxy-2-thiopyridone, prepared from tetrahydrofuran-2-carboxylic acid, D-ribofuranosylmethanoic acid, and D-ribopyranosylmethanoic acid, gave the corresponding C-nucleoside derivatives in the presence of heteroaromatic compounds via radical pathways.The essential step in this method is a radical coupling reaction of D-ribofuranosyl radical or D-ribopyranosyl radical and some heteroaromatic bases.This is a new method for the preparation of C-nucleosides using sugar carboxylic acids.

Design, synthesis and pharmacological evaluation of new acyl sulfonamides as potent and selective Bcl-2 inhibitors

The antiapoptotic protein Bcl-2, overexpressed in many tumor cells, is an attractive target for potential small molecule anticancer drug discovery. Herein, we report a different structural modification approach on ABT-263 by merging the piperazinyl-phenyl fragment into a bicyclic framework leading to a series of novel analogues, among which tetrahydroisoquinoline 13 was nearly equally potent against Bcl-2 as ABT-263. Further SAR in the P4-interaction pocket affored the difluoroazetidine substituted analogue 55, which retained good Bcl-2 activity with improved Bcl-2/Bcl-xL selectivity.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Computed Properties of C15H19NO4, you can also check out more blogs about170097-67-3

Synthesis of Dihydroindoloisoquinolines through Copper-Catalyzed Cross-Dehydrogenative Coupling of Tetrahydroisoquinolines and Nitroalkanes

Lately, the cross-dehydrogenative coupling of tetrahydroisoquinolines and nitroalkanes has become a widely studied reaction in organic chemistry; the corresponding beta-nitroamines are generally formed irrespective of the catalysis and activation mode utilized. A quite distinct behavior was observed when the reaction was catalyzed by copper nanoparticles supported on titania, leading to the formation of 5,6-dihydroindolo[2,1-a]isoquinolines with high selectivity and good yields. A meticulous reaction mechanism is proposed, based on experimentation, and discussed along with a key chemical modification of these compounds. Apparently, the catalyst effectiveness resides in its nanostructured character, outperforming the activity of the commercial copper catalysts.

Recent progress in directed evolution of stereoselective monoamine oxidases

Monoamine oxidases (MAOs) use molecular dioxygen as oxidant to catalyze the oxidation of amines to imines. This type of enzyme can be employed for the synthesis of primary, secondary, and tertiary amines by an appropriate deracemization protocol. Consequently, MAOs are an attractive class of enzymes in biocatalysis. However, they also have limitations in enzyme-catalyzed processes due to the often-observed narrow substrate scope, low activity, or poor/wrong stereoselectivity. Therefore, directed evolution was introduced to eliminate these obstacles, which is the subject of this review. The main focus is on recent efforts concerning the directed evolution of four MAOs: monoamine oxidase (MAO-N), cyclohexylamine oxidase (CHAO), D-amino acid oxidase (pkDAO), and 6-hydroxy-D-nicotine oxidase (6-HDNO).

Acetone cyanohydrin: A convenient alternative of toxic sodium cyanide/acetic acid for oxidative cyanation of tertiary amines

Acetone cyanohydrin was found to be a facile, convenient and comparatively safer alternative to toxic sodium cyanide/acetic acid system for generating in situ HCN for the oxidative cyanation of tertiary amines to alpha-aminonitriles in high yields with hydrogen peroxide using RuCl3 as catalyst. In addition organic nature of acetone cyanohydrin makes it more suitable for an organic transformation since it is readily soluble in reaction medium and can be added in a controlled manner.

Polydimethylsiloxane Sponge-Supported Nanometer Gold: Highly Efficient Recyclable Catalyst for Cross-Dehydrogenative Coupling in Water

Polydimethylsiloxane (PDMS, a stable hydrophobic polymer material) sponge-supported nanometer-sized gold can be used as a highly efficient recyclable catalyst for cross-dehydrogenative coupling of tertiary amines with various nucleophiles in water. This PDMS sponge nanometer gold catalyst can provide much better activity than the free nanometer gold in water. The reaction can be scaled up by using an easy-to-build continuous flow reactor. These results indicate the potential application of porous hydrophobic PDMS sponge material as a promising support for highly efficient recyclable catalysts in water.
