The chemical behavior of 2-methylene-2,3-dihydro-3-furanones
摘要:
Diphenylketene undergoes regioselective thermal [2+2]-cycloaddition to the heterocyclic C(3)=O carbonyl group of 5-aryl-2-methoxycarbonylmethylene-2,3-dihydrofuran-3-ones and 5-phenyl-2,3-dihydrofuran-2,3-dione to give the corresponding 3-diphenylmethylene derivatives of 2,3-dihydrofuran.
