  O-Silylated steroidal cis-aminoalcohols as chiral auxiliaries: highly diastereoselective Pd-catalyzed cyclopropanation of α,β-unsaturated aldimines

  摘要：

  alpha,beta-Unsaturated imines, obtained from cis-17-silyloxy-16-amino steroids and alpha,beta-unsaturated aldehydes, react with diazomethane in the presence of a catalytic amount of Pd(OAc)(2) with high chemo- and diastereoselectivities to form steroidal cyclopropanocarbaldimines, chromatography on silica gel gives the substituted cyclopropanocarbaldehydes with a high enantiomeric excess and allows recovery of the chiral steroidal auxiliaries.
