Abstract: | A highly enantioselective (2Z)-alk-2-enylation of aldehydes was successfully achieved by an allyl-transfer reaction from a chiral allyl donor, which was easily obtained by separation of a diastereomeric mixture of the corresponding homoallylic alcohol gamma-adducts derived from (+)-isomenthone with alk-2-enylmagnesium chloride.
