An efficient protocol for the 1,3-transposition of allylic alcohols has been developed. The method is based on the pretransformation of allylic alcohols into the corresponding epoxy mesylates, followed by the reductive elimination of the resulting epoxy mesylates by using lithium naphthalenide (LN) as a reducing agent.

The presence of a hydroxyl group has been shown to direct the regiochemistry and stereochemistry of the TCNE methanolysis of cyclohexane hydroxy-epoxides. α-Pinene epoxide underwent cleavage to form the 8-methyl ether of trans-sobrerol.
