Abstract

Substituted hydrazones <strong>5</strong> and <strong>6</strong> were synthesized by the reaction of the corresponding furo[3,2-<i>b</i>]pyrrole-5-carboxyhydrazides <strong>1</strong> with 6-substituted 4-oxochromene-3-carbaldehydes <strong>2</strong> and methyl 2-formylfuro[3,2-<i>b</i>]pyrrole-5-carboxylates <strong>3</strong> under microwave irradiation as well as by the classical method. The beneficial effect of the microwave irradiation on these reactions was a shortening of the reaction time and an increase in the yields. The reactions of <strong>1</strong> with 4-[(4-oxochromen-3-yl)methylidene]-2-phenyloxazol-5(4<i>H</i>)-one (<strong>4</strong>) were also studied. Compounds <strong>7</strong> or <strong>8</strong> were obtained, depending on the reaction temperature. <p>
