5]triazepin-4(5H)-ones have been synthesized at our laboratory as bioisosters of biologically active 1-aryl-2,3-benzodiazepine-4-ones. The efficient synthetic route described applies the synthesis of 2-(2-aroylpyrrol-1-yl)acyl hydrazides followed by ring closure under acidic conditions. The N(3)-unsubstituted title compounds thus obtained can optionally be N-alkylated rendering the preparation of variously
一个新的家庭的代表,1-芳基-3- ħ吡咯并[2,1- d ] [1,2,5]三氮杂-4(5 ħ) -酮在有我们的实验室中合成的生物活性的bioisosters 1-芳基-2,3-苯并二氮杂-4-酮。所述的有效合成路线适用于合成2-(2-芳酰基吡咯-1-基)酰肼,然后在酸性条件下闭环。所述Ñ由此获得的可任选地(3)未被取代的标题化合物Ñ烷基化渲染各种取代的衍生物可能的制备。还详细讨论了新协议的范围和局限性以及一些有趣的副反应。
