Efficient Synthesis of Butenolide−Medium Ring Ether Hybrids by a [3 + 2] Cyclization-Ring-Closing Metathesis Strategy
摘要:
GRAPHICSA new strategy for the synthesis of bicyclic gamma-alkylidenebutenolides, butenolide-medium ring ether hybrids, is reported which involves Me3SiOTf-catalyzed cyclization of 1,3-bis(trimethylsilyloxy)-1,3 butadienes with oxalyl chloride, Mitsunobu reaction, and subsequent ring-dosing metathesis.
