A practical access to alkyl- and aryl-substituted (E)-2-(azidomethyl)alkenoates and related azido compounds from the corresponding allylic bromides in aqueous acetone is described. An alternative method to obtain the starting bromides based on heterogeneous catalysis under mild conditions was also investigated.
描述了在丙酮水溶液中从相应的烯丙基溴实际获得烷基和芳基取代的(E)-2-(叠氮基甲基)链烯酸酯和相关叠氮基化合物的方法。还研究了在温和条件下基于多相催化获得起始溴化物的另一种方法。
