A new, convenient synthesis of dibenzo[ b, e ]azepin-6-ones and seven-membered sultam derivatives have been envisaged via Pd-catalyzed regioselective intramolecular Heck reaction of the corresponding easily accessible precursors. This protocol has been successfully implemented to synthesize N -methyldarenzepine in four steps and in good yield. Moreover, one of the intermediates has been utilized for the synthesis of a new analogue of darenzepine. Preliminary modeling studies were performed to investigate the binding potential to muscarinic acetylcholine receptor (M4).

(Chemical Equation Presented) Samarium(II)-mediated spirocyclization by intramolecular addition of aryl radicals onto an aromatic ring was achieved by the reaction of N-(2-iodophenyl)-N-alkylbenzamides with SmI2 in the presence of HMPA, yielding spirocyclic indolin-2-one derivatives. The ether congeners afford spirocyclic benzofuran derivatives in moderate yields by aryl radical addition onto a benzene ring without having an electron-withdrawing group. The reaction with other aryl groups such as naphthalene and indole rings is also described.
