intermediate, which undergoes attack by the activated arene subunit of the benzyl moiety. On the other hand, the Morita–Baylis–Hillman adducts of 1-formyl-N-substituted benzyl-9H-β-carbolines undergo an efficient P2O5-mediated intramolecular Friedel–Crafts reaction between the secondary hydroxy group and the activated phenyl group of the benzyl subunit to yield fused-β-carbolines. Investigations into the scope
