A Novel Approach Towards cis-and trans-Fused Pyranopyrans Based on Ring-Closing Metathesis Reaction of Carbohydrate Derivatives.

-Ring-closing metathesis of glycal-derived dienes such as (V) and (X) results in a novel synthesis of both cis-and trans-fused pyranopyrans. Their isomerization at the allylic double bond opens a new entry to fused cyclic polyethers. -(LEEUWENBURGH, M.
