Synthesis and stereoselective oxidation of α-thio-β-chloropropenyloxazolidin-2-ones
摘要:
The investigation of the stereoselective reaction of alpha-thiopropanoyloxazolidin-2-ones with NCS to yield alpha-thio-beta-chloropropenyloxazolidin-2-ones is described Diastereoselective sulfur oxidation of the resulting alpha-thio-beta-chloropropenyloxazolidin-2-ones shows modest chastereocontrol However via a combination of diastereoselective oxidation and subsequent kinetic resolution in the sulfoxide oxidation diastereoselectivities of up to 94% de have been achieved (C) 2010 Elsevier Ltd All rights reserved
