STEREOSPECIFIC CYCLISATIONS OF SUBSTITUTED α'-LITHIATED α(Z),γ-BUTADIENYL SULFOXIDES

Article abstract of DOI:10.1016/S0040-4039(00)98128-0

The title compounds 2(b-d) were prepared and converted stereospecifically to the lithiated derivatives of cyclic sulfoxides 3(b-d) through a proposed concerted disrotatory electrocyclisation.
