Abstract

<i>N</i>-[(6-substituted-4-oxochromen-3-yl)(1,2,4-triazol-3-yl)methyl]amides <strong>5</strong> and <i>N</i>-[(6-substituted-4-oxochromen-3-yl)(benzotriazol-1-yl)methyl]amides <strong>6</strong> were prepared by the reaction of 6-substituted 4-oxochromene-3-carboxaldehydes <strong>1</strong> with primary amides and 1<i>H</i>-1,2,4-triazole or 1<i>H</i>-benzotriazole. 6-Substituted 3-[hydroxy(1,2,4-triazol-1-yl)methyl]chromen-4-one <strong>2</strong> and 6-substituted 3-[hydroxy(benzotriazol-1-yl)methyl]chromen-4-one <strong>3</strong> were isolated as stable intermediates of these reactions. Beneficial effect of microwave irradiation on length of reaction time was observed. Some reactions of these derivatives with O, S, and N nucleophiles are described.
