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