γ-Amino vinyl sulfoxides in asymmetric synthesis. Synthesis of optically pure α-substituted β-amino nitriles
摘要:
The synthesis of optically pure (E)- and (Z)-gamma-amino vinyl sulfoxides derived from commercially available protected alpha-amino esters is reported. Hydrocyanation of the double bond with Et2AlCN is completely stereoselective and provides enantiomerically pure alpha-substituted beta-amino nitriles with complete control of the configuration at the alpha-carbon being exerted by the sulfinyl group.
