Chiral Acetylenic Sulfoxide in Enantioselective Synthesis of Yohimbine Alkaloid. -Michael addition of the secondary amine (I) to the chiral acetylenenic sulfoxide (II) followed by acid induced cyclization affords (III) as major product. It is a precursor of optically pure (IV), a known synthon of pe
