## Abstract 3‐Indolylalkanoic acids 2 react with benzoic acid anhydride under catalysis of Et~2~O ‐ ZnCl~2~ and mild conditions to furnish the 1‐phenyl‐substituted pyrano[3,4‐__b__]indol‐3‐ones 1c, 1d, and 3a, 3b. Products 1c, 1d, and 3b may be converted into the novel functionalized carbazoles 4 a

The role of the substitution pattern on the stability of the obtained 1.2-dihydreearbazolee is interpreted In terms of electronic and steric effects on the aromatization to the corresponding carbazoles. CH and 2-CHb bonds, a small coupling constant of 1,6 Hz is observed. A dihedral angle of about 26
