Abstract
The title sulfoxide 1 reacts with fully deuterated dimethylsulfoxonium methylide, diphenylsulfonium isopropylide and diphenyldiazomethane to form the corresponding cyclopropanes 4 as single diastereoisomers; th e chirality of the cyclopropane (+)-4c obtained from 1 and diphenyldia zomethane is (S-s,S-c) as determined by X-ray diffraction analysis; ba sed on experimental data, the steric course of the asymmetric cyclopro panation is proposed.
