Abstract
8-Formyl-4-Methyl-7-Hydroxy Coumarin Derivatives were synthesized via Penchem condensation followed by Duffs reaction. Treatment of this with N,N-di substituted cyano acetamides in the presence of piperdine afforded New 8-Formyl-4-Methyl-7-Hydroxy Coumarin Derivatives (7a-o). Their structures were characterized by IR, $^1H$ and $^{13}C$ NMR and Mass spectral and elemental analysis data.
Keywords
