Abstract

The asymmetric ene reactions of prochiral chloroaldehydes, chloral and 2,3-dichlorobutanal with 2-methylpropanal in the presence of BF3 l-menthylethyl etherate gave optically active homoallylic alcohols in 16-22% ee. The dechlorination of the chloro alcohols lead to the unsaturated derivatives of alcohols.
