摘要

Several new 4H-pyrano (2, 3-h) coumaries 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-hydroxycoumarine was reacted with the same reagents to give compounds 9a-g. The reaction of 9 g with different nucleophilic reagents afforded the pyrimido [4', 5': 6, 5] pyrano [3, 2-c] coumarin-4-one derivatives 10-12, 4-methyl-2-(ethoxymethylenamino) 4H-pyrano (3, 2-c) coumarine-3-carbonitrile (13) and pyrazolo [3', 4'; 6, 5] pyrano [3, 2-c] coumarine (14) respectively.
