furanones derivatives. These heterocyclic compounds were synthesized by reaction of 4‐(4‐bromophenyl)‐4‐oxobut‐2‐enoic acid with benzimidazole, ethyl glycinate hydrochloride, anthranilic acid and o‐phenylenediamine under Aza–Michael addition conditions. Every Aza–Michael adduct was allowed to react with haydrazine hydrate and acetic anhydride to form pyridazinones and furanones derivatives, respectively
这项研究描述了4-(4-溴苯基)-4-氧代丁-2-烯酸作为制备一系列新的芳酰基丙烯酸,哒嗪酮和呋喃酮衍生物的关键原料的实用性。这些杂环化合物是通过4-(4-溴苯基)-4-氧代丁-2-烯酸与苯并咪唑,甘氨酸乙酯盐酸盐,邻氨基苯甲酸和邻氨基苯甲酸反应而合成的苯二胺在Aza-Michael加成条件下。允许每个Aza-Michael加合物与水合hay嗪和乙酸酐反应,分别形成哒嗪酮和呋喃酮衍生物。在进一步的步骤中,使一些哒嗪酮与乙酰乙酸乙酯,乙酰丙酮,乙酰氯和芳族醛反应形成新的杂环。最后,研究了这些化合物的抗菌活性。
