, p. 2462 - 2467 (2007)
A novel organocatalytic asymmetric cyclopropanation of α,β-unsaturated aldehydes with arsonium ylides using diphenylprolinol silylether as a catalyst is described. A variety of chiral cyclopropyl aldehydes are obtained in moderate to good yields with up t
Application of novel sulfonamides in enantioselective organocatalyzed cyclopropanation
Hartikka, Antti,Slosarczyk, Adam T.,Arvidsson, Per I.
, p. 1403 - 1409 (2008/02/10)
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 phenyl ring, enabling steric, and electronic fine tuning of the catalysts. Th
