Minisci-type radical carbamoylation of 1-bromo-beta-carboline (1) gives the 3-substituted product in low yield, whereas 1-acetyl-beta-carboline (3a) reacts under ipso-substitution of the acetyl group. Cyanations of the N-oxides of 1 and 3a occur under clean ipso-substitution of the groups in I-position. I-Methyl derivatives show no tendency to react under ipso-substitution.
