[reaction: see text] A novelmanganese dioxide-mediated tandem oxidation process (TOP) has been developed which allows the direct conversion of allylicalcohols into cyclopropanes, the intermediate aldehydes being trapped in situ with a stabilized sulfur-ylide. This methodology has been applied successfully to a variety of allylicalcohols and to a formal synthesis of the simple, naturally occurring
