Bisindolyl maleimide

The indole[2,3-a]carbazole 185 possessing the rebeccamycin aglycone unit [122-132,135,136] was synthesized from the reaction of N-methyl-maleimide and 2,2/-bisindolyl 181 via Michael type addition. In the presence of aluminum trichloride, the bisindole reacts to form the Michael adducts 182 and 183. The mono-Michael adduct 182 was dehydrogenated in the presence of Pd/C in a one pot procedure to produce 184 and 185 (Scheme 43) [ 137]. [Pg.29]
