The chemistry of the Morita-Baylis-Hillman adducts of 1-formyl-β-carbolines has been extended for obtaining indolizino-indolederivatives which mimic the harmicine and homofascaplysin frameworks. Adducts of N-substituted methyl 1-formyl-9H-β-carboline-3-carboxylate yield indolizino-indolederivatives upon bromination followed by aqueous workup. On the other hand, N-substituted 1-formyl-9H-β-carbolines
