Synthesis and reactions of some new 4H-pyrano[3,2-c]benzopyran-5-one derivatives and their potential biological activities.

R M Shaker1.   

Abstract

Several new 4H-pyrano[3,2-c]benzopyran-5-ones (6a-g and 10) which exhibited antibacterial and fungicidal activity, have been synthesized via a one flask multicomponent condensation of aldehydes with malononitrile and 4-hydroxycoumarin. The reactions of 6a with several nucleophilic reagents are reported.
