Chiral non-racemic sulfoxides by asymmetric alkylation of alkanesulfenates in the presence of a chiral ammonium phase-transfer catalyst derived from Cinchona alkaloid

Gelat, Fabien,Gaumont, Annie-Claude,Perrio, Stephane

, p. 596 - 605 (2014/01/06)

Based on a previous study involving arenesulfenates, the enantioselective S-alkylation of benzyl and alkyl sulfenates R1SO- with alkyl halides, mediated by a cinchonidinium phase-transfer catalyst, was evaluated as a conceptually dif
