Quality Control of 4-Nitrobenzoic acid. Recently I am researching about PRIMARY AMINE CATALYSIS; DIELS-ALDER REACTIONS; ALPHA,BETA-UNSATURATED KETONES; ENANTIOSELECTIVE CONSTRUCTION; ASYMMETRIC-SYNTHESIS; FATTY-ACID; ADDITION-REACTIONS; MICHAEL REACTIONS; SULFUR; SULFENYLATION, Saw an article supported by the Czech Science FoundationGrant Agency of the Czech Republic [20-29336S]; Charles University Grant Agency [393615]. Published in AMER CHEMICAL SOC in WASHINGTON ,Authors: Formanek, B; Tauchman, J; Cisarova, I; Vesely, J. The CAS is 62-23-7. Through research, I have a further understanding and discovery of 4-Nitrobenzoic acid
The present report describes an organocatalytic cascade reaction between 2-alkylidene benzo[b]thiophenone derivatives and enones in the presence of the Cinchona alkaloid amine. Spirobenzothiophenonic cyclohexane derivatives containing three stereocenters were prepared via one-step synthesis in yields ranging from 88 to 96% and in enantioselectivities (enantiomeric excess (ee)) ranging from 85 to 97%, with diastereoselectivities of approximately 14/2/1. Therefore, this method provides an efficient route for the synthesis of a new class of optically active 2-spirobenzothiophenones.
