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 β-aminosulfonic acid.
