Abstract

This manuscript describes studies on structure–enantioselectivity relationships in the catalytic asymmetric intramolecular cyclopropanation (IMCP) reaction of α-diazo-β-keto sulfones possessing a methyl-substituted phenyl group. Enantioselectivity of the IMCP reaction of the α-diazo-β-keto sulfones was varied by the position of a methyl group on the phenyl group in the substrate, and the 2, 3-dimethylphenyl sulfone 11h provided the ...
