摘要

Abstract 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 was photocyclization ...
