The heterocyclization of 2-acetyl-3-indolylacetic acid hydrazones and its amides, in contrast to similar derivatives of phenylacetic acid, does not lead to 2,3-dihydro-2-oxo-5-R1-1H-[1,2]diazepino-[4,5-b]indoles but rather to 2-aminoindolo[2,3-

The synthesis of a number of 2-anilino- and 2-(benzoyl-amino)-β- carbolin-3-ones in good yields by a one-step sequence from the reaction of pyranoindolones with phenylhydrazine or benzoylhydrazine is described; the observed good regioselectivity of the reaction is discussed. Full assignment of all 1H and 13C NMR chemical shifts has been unambiguously achieved.
