摘要：

The trifluoroacetic anhydride promoted Pummerer reactions of N-Cbz alpha-amino-alpha-trifluoromethyl-beta-p-tolylsulfinyl methyl butanoates 1b-c occur in a highly stereospecific non-oxidative fashion (d.r. > 98:2), resulting in a S(N)2-lype displacement of the sulfinyl by hydroxy group and providing enantiomerically pure alpha-trifluoromethyl-allo-threonine 2b and -threonine 2c derivatives.
