substrates are readily prepared from both aryl and aliphatic ketones, where the regioselective preparation has long been known utilizing a variety of methods. The power of this methodology lies in its ability to quickly produce a diverse set of single enantiomer products using different allylic alcohols with a common prochiral enol acetate. This is demonstrated here by two rapid formal syntheses of hamigeran
