Intramolecular photoaddition reactions of 2-(ω-alkenyl)isoquinolin-1(2H)-ones and 1-(ω-alkenyl)pyridin-2(1H)-ones were examined, and the regioselectivity and dependence of these reactions on the length of methylene chain in the alkenyl group were clarified.By utilizing these reactions, a synthetic route to indolizine and quinolizine derivates was elaborated.By an extension of this approach to the intermolecular reaction, 6-methoxy-3-methyl-1,2-dihydrocyclobutapyridin-4(3H)-one was synthesized from 4,6-dimethoxy-1-methylpyridin-2(1H)-one.Keywords-2+2 photocycloaddition; intramolecular photoaddition; photocycloreversion; annelation; indolizine; quinolizine; cyclobutapyridine; 4,6-dimethoxypyridin-2(1H)-one; 1-(ω-alkenyl)pyridin-2(1H)-one; 2-(ω-alkenyl)isoquinolin-1(2H)-one
