An efficient and broadly applicable alternative to the classical Pictet-Spengler synthesis of tetrahydro-beta-carbolines is presented. The method relies on metal-catalyzed isomerization of allylic amines to form reactive iminium intermediates which can be trapped by a tethered indole nucleophile.
提出了一种有效且广泛适用的四氢-β-咔啉的经典Pictet-Spengler合成方法。该方法依赖于烯丙基胺的金属催化异构化以形成反应性亚胺中间体,该中间体可以被束缚的吲哚亲核试剂捕获。
