Recently I am researching about CASCADE REACTIONS; MICHAEL REACTION; CONDENSATIONS; CONSTRUCTION, Saw an article supported by the Shanghai Pujiang ProgramShanghai Pujiang Program [KBH1615505]. Name: 4-Nitrobenzoic acid. Published in AMER CHEMICAL SOC in WASHINGTON ,Authors: Hu, S; Wang, JQ; Huang, GX; Zhu, KJ; Chen, F. The CAS is 62-23-7. Through research, I have a further understanding and discovery of 4-Nitrobenzoic acid
An organocatalytic asymmetric enantioselective domino oxa-Michael-Mannich-[1,3]-amino rearrangement reaction of N-tosylsalicylimines with a wide range of alpha,beta-unsaturated aldehydes utilizing diarylprolinol silyl ether catalysis is described. The catalytic reactions proceed with excellent enantioselectivity (up to 99% ee) to produce the corresponding chair N-tosylimines-chromenes with a yield of up to 99%, tolerating a range of functional groups. This methodology offers a new method with great potential to further extend the synthetic power and versatility of chiral aminocatalysis.
