SIMPLE CHIRAL CROWN ETHERS COMPLEXED WITH POTASSIUM TERT-BUTOXIDE AS EFFICIENT CATALYSTS FOR ASYMMETRIC MICHAEL ADDITIONS

Simple C2-symmetric chiral crown ether 1 complexed with KOtBu was found to work as an efficient chiral catalyst in Michael additions to cause high asymmetric induction.The results with various chiral crown ethers as catalysts suggest that diaxial-like conformation of the vicinal methyl groups of 1<*>potassium enolate complex is responsible for the chiral induction.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms.In my other articles, you can also check out more blogs about4254-15-3.Application In Synthesis of (S)-Propane-1,2-diol

METHOD FOR TREATING SUGAR SOLUTION, HYDROGENATED SUGAR SOLUTION, METHOD FOR PRODUCING ORGANIC COMPOUND, AND METHOD FOR CULTURING MICROORGANISMS

Provided are a method for treating a saccharide solution, which comprises subjecting a saccharide solution containing at least one selected from the group consisting of a carbonyl compound and an unsaturated alcohol other than a saccharide to hydrogenation reaction to hydrogenate the carbonyl compound and/or the unsaturated alcohol contained in the saccharide solution, a hydrogenated saccharide solution obtained by treating with the treatment method, and a method for producing an organic compound having a process of obtaining the organic compound by acting a microorganism having an organic material producing ability on an organic raw material containing the hydrogenated saccharide solution.

Asymmetric ring-opening of epoxides on chiral Co(Salen) catalyst synthesized in SBA-16 through the “ship in a bottle” strategy

Chiral Co(Salen) complex was synthesized in the mesoporous cage of SBA-16 through the “ship in a bottle” method. The pore entrance size of SBA-16 was precisely tailored by varying the autoclaving time and silylation with phenyltrimethoxysilane to trap Co(Salen) complex in the cage of SBA-16. Chiral Co(Salen) trapped in SBA-16 shows enantioselectivity (up to 87-96% ee) as high as that of the homogeneous catalyst for the asymmetric ring opening of terminal epoxides and can be recycled at least 10 times with no apparent loss of activity. The activity for the catalyst trapped inside SBA-16 can be significantly increased when the surface is modified with organic groups. This work extends the “ship in a bottle” synthesis from microporous materials to mesoporous cage-like materials and develops an effective strategy to trap metal complex catalyst with large molecular size into the nanopores or cavities of mesoporous materials.

A RhCl(PPh3)3/BF3¡¤OEt2 co-promoted direct C-C cross-coupling of alcohols at beta-position with aldehydes

A novel RhCl(PPh3)3/BF3¡¤OEt2 co-promoted direct C-C cross-coupling of primary and secondary alcohols at beta-position with aldehyde was developed. This reaction could provide an efficient synthesis of a series of alpha,beta-unsaturated aldehydes and diarylidene ketones, just from simple and easily available alcohols and aldehydes.

Chlorination of benzylic and allylic alcohols with trimethylsilyl chloride enhanced by natural sodium montmorillonite

A new and practical method for the efficient chlorination of tertiary, secondary, and primary benzylic and allylic alcohols is described. The method is characterized by the formation of hydrogen chloride from trimethylsilyl chloride and trace water, the formation of a carbenium ion through the protonation of an alcohol and subsequent dehydration, and the chlorination of the carbenium ion. During the process, sodium ion-exchanged montmorillonite plays a crucial role in capturing the generated hydrogen chloride, stabilizing the carbenium intermediate as well as promoting the chlorination.
