Abstract

The synthetic routes of 6,7‐dihydrobenzo[4,5]cyclohept[1,2‐b]indol‐12(5__H__)‐one 5 from either 1‐methyl or 1‐sulfonylindole‐2‐carboxaldehyde 1 or ethyl 1,2‐dimethylindole‐3‐carboxylate 6 are reported. The structure of the ketone 5a was confirmed by X‐ray crystallography. Several indole derivatives have been prepared with potential antitumor activity.
