designed as potential anticancer agents. An efficient synthesis involving palladium-catalyzed Suzuki and Stille reactions is presented, without any indolic protective group. The central ring closure of the scaffold was performed through an electrophilic reaction on the position C-2 of the indole ring. The use of indole and 5-benzyloxyindole, along with substituted phenyl rings, generated three different
were interested in the synthesis of mixed structures of maleimidophenyl carbazoles and natural product caulersine as potential CDK inhibitors. This was performed through an efficient four-step sequence starting from indole or 3-formyl-N-Boc indole. 5H-Benzocycloheptaindol-6-one derivatives equipped with a fused maleimide (oxophenylarcyriaflavins) or a methyl ester (benzoanalog of caulersine) on the
