  Catalytic asymmetric synthesis of protected α-hydroxy aldehydes and related 1,2-difunctional chiral building blocks. An enantioselective synthesis of (−)-exo- and (−)-endo-brevicomin

  摘要：

  Chiral allylic alcohols which were prepared by the addition of functionalized dialkylzincs to alpha,beta-unsaturated aldehydes in good to excellent enantioselectivity, were converted to protected alpha-hydroxy aldehydes and 1,2-amino alcohols without loss of enantiomeric purity. Syn- or anti-1,2-diols can be obtained stereoselectively by a second asymmetric addition to alpha-silyloxy aldehydes. Functionalized 1,2-diols prepared in this way were converted to enantiomerically pure (-)-exo- and (-)-endo-brevicomin (>99% ee). (C) 1997 Elsevier Science Ltd.
