Tricyclic keto-indoles were synthesized by photocyclization of easily obtained enaminones in an electro-cyclic photochemical reaction. The three methods reported were chosen according to the enaminone structure. The most general procedure using one-step synthesis was carried out in a benzene-methanol solution in the presence of sodium methylate. In the case of base sensitive substrates, the best method
在环光化学反应中,通过容易获得的烯胺酮的光环化反应合成了三环酮吲哚。根据烯胺酮结构选择报道的三种方法。使用一步合成的最通用方法是在甲醇钠存在下的苯甲醇溶液中进行的。对于碱敏感的底物,最好的方法是光环化然后氧化。此外,通过光解反应制备了具有五元环的N-未取代的吲哚。这三种方法都是高效且易于执行的。
