Abstract We report herein a new convergent one pot method for the synthesis of amino benzyl ethers containing a bicyclic amine, derived from different substituted benzyl alcohols and bicyclic amino alcohols such as tropine, pseudotropine, and 3-quinuclidinol, using chlorotrimethylsilane and sodium iodide. In order to avoid the competitive reaction with the nitrogen atom, a solution of the separately
摘要 我们在此报告了一种新的聚合一锅法,用于合成含有双环胺的氨基苄基醚,该氨基苄基醚衍生自不同的取代苄醇和双环氨基醇,如托品、赝托品和 3-奎宁环,使用三甲基氯硅烷和碘化钠。为了避免与氮原子的竞争反应,将单独制备的托品、拟托品和3-奎宁环醇的醇盐溶液加入到预先形成的取代苄基碘中,并在氮气氛下在90℃回流15小时. 与现有方法相比,该方法为有机合成中氨基苄基醚的制备提供了一种有效的替代方法,收率良好。图形概要
