Silver-Catalyzed Highly Regioselective Synthesis ofα-Carbonyl Furans from Enynones
摘要:
A general and efficient method for the synthesis of a wide range of alpha-carbonyl furans is described here. The cyclization of enynone is catalyzed by AgBF4 in a fluorous biphasic system of perfluorodecalin and N,N-dimethylformamide. A variety of chain ketone and cyclic ketone substrates were used to investigate the scope of the reactions.
