Abstract

The condensation of 5- and 6-aminoindoles with diketene and acetoacetic ester was realized. A convenient method for the synthesis of pyrrolo[3,2-f]- and pyrrolo-[2,3-f]quinol-9-ones from 5- and 6-aminoindoles was developed. Under the influence of trifluoroacetic acid acetoacetic acid amides gave a mixture of 2,3,8-trimethylpyrrolo[2,3-g]quinol-6-one and 1,2,9-trimethyl-pyrrolo[3,2-f]quinol-7-one (in the case of 5-aminoindole) and a mixture of 2,3,5-trimethylpyrrolo [3,2-g]-quinol-7-one and 2,3,9-trimethylpyrrolo[2,3-f]quinol-7-one.
