Abstract

The reaction of 6-amino-2,3-dimethyl-  and  6-amino-1,2,3-trimethyl-5-methoxy(methyl)indoles with 4,4,4-trifluoroacetoacetic ester and of 6-amino-5-methoxy-1,2,3-trimethylindole also with  other β-dicarbonyl compounds has been studied. It was found  that all of the amines investigated undergo condensation readily to form the corresponding enamines while the possible subsequent cyclization to give pyrrolo[2,3-f]quinolines was found only for the condensation product of 6-amino-2,3,5-trimethylindole with 4,4,4-trifluoroacetoacetic ester.
