  Enantioselective Synthesis of Quaternary α-Aminophosphonates via Conjugate Addition of α-Nitrophosphonates to Enones

  摘要：

  Enantioselective Michael addition of alpha-nitrophosphonates to enones for the synthesis of alpha-aminophosphonates is reported for the first time. The reaction proceeds in good to high yields and moderate to high selectivity in the presence of a new quinine thiourea catalyst. The quaternary nitrophosphonates were conveniently transformed to cyclic quaternary alpha-aminophosphonates via in situ reduction intramolecular cyclization or Baeyer-Villiger oxidation followed by in situ reduction intramolecular cyclization.

• Enantioselective synthesis of diethyl 1-hydroxyalkylphosphonates via oxazaborolidine catalyzed borane reduction of diethyl α-ketophosphonates

  DOI：10.1016/s0957-4166(00)86271-0

  日期：1994.10

  Reduction of diethyl alpha-ketophosphonates 1 with borane and B-butyloxazaborolidine 2 as catalyst afforded diethyl (S)- or (R)-1-hydroxyalkylphosphonates 3a-d or 3e-f respectively in good yields and moderate to good enantiomeric excess (53-83 ee%). Respective diethyl (R)- and (S)-1-aminoalkylphosphonates 6 were obtained in a one-pot transformation, by the Mitsunobu reaction of 1-hydroxyphosphonates 3 with hydrazoic acid, and subsequent treatment of the intermediate azides 4, with triphenylphosphine, followed by hydrolysis df the iminophosphoranes 5 with water.
