A one-pot synthesis of the 2,3-dihydro-1H-pyrrolo[3,2-c]quinoline core from substituted 2-iodoanilines and 2,3-dihydro-1H-pyrrole was achieved using 10 mol % Pd(PPh3)4, and K2CO3 in 1,4-dioxane at 170 °C for 1 h in a microwave oven. This reaction can be carried out on a gram scale. The proposed mechanism involves a Heck-coupling reaction followed by intra-molecular Schiff base formation and double
使用10 mol%Pd()可以由取代的2-碘苯胺和2,3-二氢-1 H-吡咯一锅法合成2,3-二氢-1 H-吡咯并[3,2- c ]喹啉核将PPh 3)4和K 2 CO 3在1,4-二恶烷中的溶液在170°C的微波炉中加热1小时。该反应可以以克为单位进行。拟议的机制涉及Heck偶联反应,然后在分子内席夫碱形成和双键迁移。
