Microwave Assisted, L-Tyrosine Catalyzed Efficient Synthesis of Tetrahydrobenzo[b] Pyrans

A mild and efficient protocol has been developed for the synthesis of Tetrahydrobenzo[b]pyrans, from aldehyde, malononitrile and dimedone in presence of L-Tyrosine under Microwave irradiation. High yield, simple workup procedure and mild reaction condition are main feature of this protocol.
