A new synthesis of α-carbolines was developed starting from the easily accessible 3-substituted indol-2(3H)-one derivatives 2 and enamines 3. The intermediates 4 afforded the α-carbolines 5 and 6 by thermal cyclization with ammonium acetate in glacial acetic acid by way of pyridine ring formation.
从容易获得的3-取代的吲哚-2(3 H)-one衍生物2和烯胺3开始开发了一种新的α-咔啉合成方法。中间体4通过在吡啶乙酸中通过乙酸铵形成吡啶环而与乙酸铵进行热环化而得到α-咔啉5和6。
