Design of new anticancer drugs. II. Easy arynic access to benzocyclobutacarbazoles, a new family of antitumor agents
摘要:
Tetrahydrobenzocyclobutacarbazoles with antitumoral properties were obtained either by arynic condensation of aryl halides with 3-carbazolone enolates or arynic cyclisation of halogenated arylimine enolates of 2-biphenylenones in the presence of the complex base NaNH2-tBuONa.

Several benzocyclobutacarbazol derivatives were synthesized and evaluated for their potential cytotoxic properties. A number of these compounds exhibited significant antiproliferativeactivity with concomitant interaction with the cell cycle and represent a newclass of potential anticancer agents.
