Preparation of α-vinylidene-γ-lactones by palladium-catalyzed carbonylation of 5-hydroxy-2-alkynyl methyl carbonates under mild conditions
摘要:
Carbonylation of 5-hydroxy-2-alkynyl methyl carbonates catalyzed by Pd(OAc)(2) in the presence of a bidentate phosphine takes place under mild conditions to afford alpha-vinylidene-gamma-lactones in good yields.
