On July 4, 2007, Hartikka, Antti; Slosarczyk, Adam T.; Arvidsson, Per I. published an article.Recommanded Product: H-Idc-OH The title of the article was Application of novel sulfonamides in enantioselective organocatalyzed cyclopropanation. And the article contained the following:
Three novel aryl sulfonamides derived from (2S)-indoline-2-carboxylic acid have been obtained and used as organocatalysts. The catalysts incorporate diverse functionality on the Ph ring, enabling steric, and electronic fine tuning of the catalysts. The catalysts facilitate the reaction between a range of α,β-unsaturated aldehydes and sulfur ylides, thus providing cyclopropane products in enantiomeric excesses of up to 99%. E.g., reaction of (E)-MeCH:CHCHO and Me2S+C-HCOPh gave 45% cyclopropane I (88% ee). The experimental process involved the reaction of H-Idc-OH(cas: 79815-20-6).Recommanded Product: H-Idc-OH
