- Synthesis of new pyrrolo[3,4-b]indol-3-ones as latent substrates for pyrrolo[3,4-b]indoles
-
We report the synthesis of new examples of the 1,4-dihydropyrrolo[3,4-b]indol-3(2H)-one ring system via Fischer indolization between the appropriate phenylhydrazines and pyrrolidine-2,3-diones. Lithiation at the C-1 position with lithium diisopropylamide following by quenching with iodomethane affords 1-methyl-1,4-dihydropyrrolo[3,4-b]indol-3(2H)-ones in excellent yield.
