  Diastereoface Discrimination in the Addition of Acetylide to a Chiral Aldehyde, Leading to a Synthesis of (+)-Deoxybiotin in Enantiomerically Pure Form Starting from L-Cysteine

  摘要：

  Complete diastereofacial discrimination was observed upon addition of the chlorozinc acetylide derived from 1-hexyne to a chiral aldehyde prepared from L-cysteine. The addition product was used in a short synthesis of (+)-deoxybiotin, a precursor of (+)-biotin, which was produced in enantiomerically pure form in 12 steps, starting from L-cysteine.
