A. Mouaddib et al., Synthesis of 6-substituted 5,6,7,12-tetrahydrobenzo[4,5]-cyclohept[b]indol-12-one derivatives, HETEROCYCLE, 51(9), 1999, pp. 2127-2137
The synthesis of 6-substituted 5,6,7,12-dihydrobenzo[4,5]cyclohept[b]indole
derivatives, through a regioselective alkylation of 1 in position-6, is re
ported. The antiproliferative activity of 18 was evaluated.
