Abstract
AbstractSynthesis of title compounds were accomplished by a reaction of vinyl malononitriles and arylidene pyrazolones catalyzed by base. This protocol proceeds via Michael addition followed by intramolecular cyclization leading to the formation of two new C−C bonds. Further the same reaction was also conducted with α,α‐dicyano olefins and vinyl malononitriles to furnish 1,6‐dihydro biphenyl compounds. Simple reaction conditions, high yields and compatibility are the advantages of this protocol.
