- One-pot synthesis of pyrrolo[3,2-f]-and pyrrolo[2,3-h]quinoline derivatives: Observation of an unexpected mechanistic pathway
-
One-pot synthesis of pyrrolo[3,2-f]- and pyrrolo[2,3-h]quinolines were obtained starting from substituted 5-aminoindoles, benzaldehydes, and phenylacetylenes in the presence of La(OTf)3 as a catalyst in good yields. The indole moiety in 5-aminoindole is believed to be mainly responsible for the observation of unexpected mechanistic pathway to the formation of pyrrolo[2,3-h]quinoline.

- Synthesis of pyrrolo[2,3-H]quinolines from 4-amino-2,3-dimethyl-and 4-amino-1,2,3-trimethylindoles
-
A study was carried out on the reactions of 4-amino-2,3-dimethyl-and 4-amino-1,2,3-trimethylindoles with acetylacetone, dibenzoylmethane, ethyl acetoacetate, ethyl trifluoroacetoacetate, and ethyl oxaloacetate. Methods were developed for the synthesis of a series of substituted pyrrolo-[2,3-h] quinolines.
