chromen-3-yl)-4-pyridine-3-carbo-nitriles were synthesized by the one-pot, multicomponent reaction of 3-acetyl-coumarin, aromatic aldehydes, malononitrile, and ammonium acetate in acetic acid under microwave irradiation. The reactions were completed in 10–13 min with 61–86% yields, were environmental benign, and had easy workup. Their structures were confirmed by 1H NMR, IR, and MS spectra and elemental
摘要 通过3-乙酰香豆素的一锅多组分反应合成了一系列2-氨基-6-(2-oxo-2H-chromen-3-yl)-4-pyridine-3-carbo-nitriles,芳香醛、丙二腈和醋酸铵在微波辐射下的醋酸中。反应在 10-13 分钟内完成,产率为 61-86%,对环境无害,并且易于处理。它们的结构通过 1H NMR、IR、MS 光谱和元素分析得到证实。
