Abstract
Azaindol-2(3H)-ones have stimulated little interest, the only successful syntheses being 7-azaoxindole 1,2,3,3-dimethyl-7-azaoxindole3 and recently 4-azaoxindole4, whilst several have been unsuccessful 5,6. Following our studies in the oxindole series 7 we now wish to describe a short synthesis of the novel azaoxindole title compounds.
