Highly asymmetric Pummerer-type cyclization of chiral, non-racemic β-amido sulfoxides

The first highly asymmetric Pummerer-type cyclization of chiral, non-racemic β-amido sulfoxides to enantiomerically enriched β-lactams (80-85percent ee) is described.S- and R-Silfoxides (S-2a-d and R-2a-c) were treated with O-methyl-O-tert-butyldimethylsi
