چکیده
|
A highly efficient and simple procedure for the synthesis of 4h-benzo[b]pyrane derivatives is described. the reaction of 5,5- dimethylcyclohexane-1,3-dione or cyclohexane-1,3-dione with aromatic aldehydes and malononitrile using catalytic amount of alumina supported kf in reflux ethanol affords the title compounds in high to excellent yields and in short reaction times. © 2012 hindawi publishing corporation.
