Condensation of 3‐cyano‐7‐diethylamino‐ N ‐ethoxycarbonyl‐iminocoumarin with various hydrazides as N‐nucleophiles gave a new series of 2‐oxo‐2 H ‐1‐benzopyrano[2,3‐ d ]pyrimidines bearing an acylhydrazino fragment in the 4‐position. The structures of the products obtained were characterized using IR, 1 H NMR, 13 C NMR and elemental analysis. The optical properties were reported for three of these compounds. J.
