چکیده
|
A facile,simple and convenient method for the synthesis of 4. h-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. with the optimized reaction conditions,the desired products were obtained with 62-82% yields. © 2012 production and hosting by elsevier b.v.
