Furans are particularly attractive four-carbon building blocks because they are readily accessible and have unique reactivity that allows for the construction of diverse significant molecules1.With increasing use of furans as a renewable source of raw materials,the developmet of new methods,especially based on its diene-characterized properties,for transformations of furans into other useful compounds is receiving much attentions from both circles of organic and resource chemistry.In a continuous interest in the dearomatization of furan ring2.
