Abstract

A FeCl3-promoted synthesis of spiro[4.5]decane derivatives has been developed from 2-(5,5-dimethoxypentyl)-1-substituted cyclopentanols with high diastereoselectivity. These interesting compounds are formed through a cascade process involving a FeCl3-promoted dehydration of alcohol followed by FeCl3-mediated Prins cyclization.
