摘要：

The reaction of (-)1R or (+)-1S-tricarbonyl(2-substituted benzaldehyde)chromium complexes with tertbutylmethanesulfonamide dianion afforded, after decomplexation and intramolecular cyclization the enantiomerically pure N-tert-butyl-3-(2-phenyl substituted)-1,2-thiazetidine 1,1 dioxide derivatives. The hydrolytic ring opening gave the corresponding enantiopure beta-aminosulfonic acid. (C) 1999 Elsevier Science Ltd. All rights reserved.
