  Asymmetric Cyclopropanation Using New Chiral Auxiliaries Derived from D-Fructose

  摘要：

  Acetals of alpha,beta-unsaturated aldehydes with 3-O-alkylated derivatives of 1,2-O-isopropylidene-beta-D-fructopyranose and 1,2-O-isopropylidene-beta-D-psicopyranose, which are readily available from D-fructose, were cyclopropanated with Et(2)Zn and CH2I2 with good diastereoselectivity. The effects of structure of the acetals on enantioselectivity were examined.
