The invention relates to novel indole and heteroindole derivatives of the formula I
1
to their tautomers, their stereoisomers, their mixtures and their salts, to their preparation and to the use of indole derivatives of the formula I as antitumor agents.
Functionalization at C-2 and C-5 of N-benzenesulfonyl-4-azaindole 1 was performed by lithiation reactions and original palladium-catalyzed chemistry. It led to very useful new substituted 4-azaindole derivatives in fair to high yields.
