Abstract

Cyclopropanation of chiral alpha-alkoxy acrylamides derived from 1R,2S-ephedrine and alpha-keto acids provides cyclopropyl morpholinones with good diastereoselectivity. Removal of the ephedrine portion generates alpha-hydroxycyclopropane carboxamides which are readily converted to enantiomerically enriched alpha-hydroxycyclopropanecarboxylic acids.
