described a mild and easy method, in two steps, by which various benzyl groups were introduced in the C-2 position of tryptamine. The first step consisted on the synthesis of β-carbolines, starting from tryptamine derivatives, by a Pictet–Spengler reaction. Ring-opening of the β-carbolines, by hydrogenation, led to the desired 2-substituted benzyl tryptamine indole products. A supplementary step of alkylation
我们分两步描述了一种温和而简便的方法,通过该方法,将多种苄基引入色胺的C-2位置。第一步包括通过Pictet-Spengler反应从色胺胺衍生物开始合成β-咔啉。通过氢化使β-咔啉开环,得到所需的2-取代的苄基色胺为吲哚产物。可以实现烷基化的补充步骤,以得到N-烷基-2-取代的苄基色胺。在这些反应过程中,氮原子不需要任何保护步骤。
