Reaction of pyrano[3,4‐b]indolones with aliphatic amines and N,N‐dimethylhydrazine

Abstract magnified image The synthesis of a number of indolylacetamides and indolylacetohydrazides in very good yields from the reaction of pyranoindolones with aliphatic amines and N,N‐dimethylhydrazine, respectively, is described. The reactivity difference with aromatic amines but also with methylhydrazine and aromatic hydrazines is discussed. J. Heterocyclic Chem., (2010).
