Terminal alkynes are easily transformed into enantiomerically enriched compoundscontaining tertiary and quaternarycarbonatoms. Sulfinylation followed by reduction (or alkylation) and hydrocyanation of the resulting vinyl sulfoxides with Et2 AlCN provides nitriles bearing the chiral center, which can in turn undergo reaction to form the desired products.
