In this thesis, the Lewis acid initiated and visible-light-promoted intramolecular alpha-alkylation and alpha-alkenylation of alpha,beta-unsaturated lactams and lactones have been developed. The reaction products are exclusively six- and seven-membered rings, respectively, with high regioselectivity and good functional groups tolerance. These reaction protocols allow efficient functionalization of quinolinones and coumarins with non-activated olefins, which were not accessible with previous methods.
