A magnetic nano‐supported Cu(I) catalyst was prepared and showed high activity for cyclization of ene‐yne‐ketone to synthesize furans. The catalyst was easily recovered from the reaction by using external magnets and reused 8 times without significant loss of its catalytic activity.

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.
