The stereospecific and regiospecific addition of butyl tellurolates to terminal acetylenes containing a phenyl group, a propynyl unit and a 2-butenol system first produces Z-vinyl tellurides 3, 4, 5 which are directly metallated with higher-order cyanocuprates to the corresponding Z-vinyl cuprates ; these cuprates in turn have been added to a series of simple epoxides and vinyl epoxides to produce functionalized homoallylic alcohols.
