iodide-promoted efficient synthesis of pyrimidines from biomass-based alkyl lactates, inorganic ammonium, and aldehydes was carried out. This multicomponent reaction efficiently proceeded through a series of condensation, dehydrogenation coupling, and condensation steps to form C–N and C–C bonds, respectively. This protocol strikingly features sustainable catalysis using Earth-abundant metals and NH4I
铁(III)和碘化物促进从生物质基乳酸烷基酯、无机铵和醛有效合成嘧啶。这种多组分反应通过一系列缩合、脱氢偶联和缩合步骤有效地进行,分别形成C-N和C-C键。该协议的显着特点是使用地球丰富的金属和 NH 4 I 作为底物和催化剂进行可持续催化。当使用生物质基乳酸烷基酯作为原料时,乳酸烷基酯可以重复使用,并且可以获得清洁的副产物。合成了 30 多种嘧啶和 7 种三嗪,分离收率高达 92%。此外,对绿色指标几个维度的分析也证明了本工作的绿色性。这项工作代表了生物基醇和无机盐在可持续有机合成中的有前景的应用。
