摘要

Eight new chiral 2-thiazolines (4, 5-dihydro-1, 3-thiazoles) 2 have been prepared by treatment of the 2-methyloxazolines 1, the benzoylamino alcohols 4 or the trimethylacetylamino alcohols 5 with P2S5. With a 2-methyl substituent, reaction with Oxone® results in ring-opening to give the acetylamino disulfides 9 and with MCPBA there is also ring-opening with incorporation of a m-chlorobenzoyl group to give 12.
