The assignment of the olefin geometry was conducted by NOE experiment between the olefinic proton and the cis-substituent. High optical purity of 4a was confirmed by chiral HPLC (Daisel Chiralcel OB) in comparison with the racemic sample.

Posner and Okamura independently reported that α-sulfinyl vinyllithium generated by α-deprotonation of (Z)-vinylic sulfoxide immediately isomerizes to thermodynamically stable (E)-isomer (Posner, G. H.; Tang, P.-W.; Mallamo, J. P. Tetrahedron Lett. 1978, 3995-3998. Okamura, H.; Mitsuhira, Y.; Miura, M.; Takei, H. Chem. Lett. 1978, 517-520). In sharp contrast, no E/Z-isomerization was observed in α-sulfinyl vinylic carbanion generated by conjugate addition of organocopper reagents to 1-alkynyl sulfoxides (ref 4). The difference presumably arises from the ionic nature of the carbon-lithium bond as compared with the carbon-copper bond. With these facts in mind, we speculate that the organomagnesium intermediate in the reaction of Scheme 1 is geometrically more unstable due to its ionic nature than the corresponding organozinc intermediate in carbozincation, thereby suffering from E/Z-isomerization.
