摘要：

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