  Chiral (o-Hydroxyaryl)oxazaphospholidine Oxides: A New Class of Bifunctional Catalysts in the Enantioselective Borane Reduction of Ketones

  摘要：

  The synthesis of a new class of bifunctional organophosphorus catalysts for the asymmetric borane reduction of prochiral ketones has been investigated. Keys to the architecture of effective catalysts are an oxazaphospholidine structural unit and a hydroxyaryl moiety. These (o-hydroxyary-1)oxazaphospholidine oxides have been successfully applied to the catalytic (2 mol-%) asymmetric borane reduction of numerous prochiral ketones with enantiomeric excesses up to 84% ee.

  STUDIES ON CHIRAL THIOPHOSPHORIC ACIDS AND THEIR DERIV ATIVES 16.-THE ASYMMETRIC CYCLIZATION OF L-(+)- PROLINOL WITH (THIO)PHOSPHORO(-NO)DICHLORIDATES

  摘要：

  The cyclizations of L-(+)-prolinol 5 with (thio)phosphoro(-no)dichloridates 6 give 1,2,3-azaphosphaoxabicyclo[3.3.0]octanes 7 consisting of unequal amounts of diastereoisomers, eight pairs of which have been successfully resolved by silica gel column chromatography or recrystallization. The influences of reaction temperature, solvent and substrate concentration upon the asymmetric induction have also been investigated.

  日期：——

  Eleven chiral trivalent or quatrivalent phosphorus reagents were synthesized starting from L-proline, D-camphor, (+)- or (−)-1,1′-binaphthalene-2,2′-diol, (−)-α-phenylethylamine, etc. and their application as catalysts in asymmetric borane reduction of N-phenyl imine of acetophenone was preliminarily investigated. N-Phenyl α-phenylethylamine was obtained in good yield with low to moderate enantioselectivity
