Propargylic oxiranes 4a-e and aziridines 8a-c have been prepared from cinnamyl chloride through lithiation-alkylation with alpha -halo carbonyl compounds and alpha -chloro imines, respectively. The reaction with substituted alpha -halo carbonyl compounds and alpha -chloro imines proved to be highly E diastereoselective.
