Nitriles in Heterocyclic Organic Synthesis: Synthesis of Pyrano[2,3-h]coumarines, Pyrano[3,2-c]coumarines, and their Derivatives

Several new 4H-pyrano[2,3-h]coumarines 5a-e were prepared by the reaction of 7-hydroxycoumarine with cinnamonitriles 1. Also, the reaction of 7-hydroxycoumarine with a mixture of aliphatic aldehydes and malononitrile afforded compounds 5f,g. Similarly, 4-
