Abstract
GRAPHICS A new strategy for the synthesis of bicyclic gamma-alkylidenebutenolides, b utenolide-medium ring ether hybrids, is reported which involves Me3SiOTf-ca talyzed cyclization of 1,3-bis(trimethylsilyloxy)-1,3 butadienes with oxaly l chloride, Mitsunobu reaction, and subsequent ring-dosing metathesis.
