(matrix presented) A new strategy for the synthesis of medium-sized bicyclic γ-alkylidenebutenolides is reported which involves Me3SiOTf-catalyzed cyclization of cyclic 1,3-bis(trimethylsilyloxy)-1,3-butadienes with oxalyl chloride.

Medium-sized bicyclic γ-alkylidenebutenolides were efficiently prepared by Me3SiOTf-catalyzed cyclization of cyclic bis(silyl enol ethers) with oxalyl chloride. In addition, a new strategy for the synthesis of medium-sized bicyclic hybrids of b
