This study was initiated by
7-hydroxy-4-methylcoumarin 1
synthesis according to the Peckmann reaction with resorcinol and
ethylacetoacetate. This compound was
converted into 8-formyl-7-hydroxy -4-methylcoumarin 2 compound by the Duff
reaction. This aldehyde obtained was
reacted with 6-amino-1,4-benzodioxane and 2-amino benzamide, which have their
specific biological activities, to synthesize the original two novel compounds.
While 3 (7-Hydroxy-4-methyl-8-[(2,3-dihidro-1,4-benzodioxin-6-yl)iminomethyl]-2H-1-benzopiran-2-on)
is obtained as a coumarin schiff base, ring closure was observed at 4 (2-(2’-Hydoxy-5-methyl
coumarin-1-yl)-2,3-dihidro quinazoline-4(1H)-on). Our
compounds are thought to exhibit biological activity. Their structures were
identified by IR, 1H NMR, 13C
NMR , MS analysis.
