Piperazine catalyzed convenient synthesis of 4H-pyran derivatives from α,α′-bis(substituted-benzylidene) cycloalkanones and malononitrile under reflux conditions

Piperazine catalyzed convenient synthesis of 4H-pyran derivatives from α,α′-bis(substituted-benzylidene) cycloalkanones and malononitrile under reflux conditions

A facile, simple and convenient method for the synthesis of 4H-pyran derivatives has been achieved through the condensation reactions of α,α′-bis(substituted-benzylidene) cycloalkanones and malononitrile in the presence of piperazine as an odorless and easy to work catalyst under reflux conditions....
