Photochemical reactions of phthalimides having various carbonyl functions (amides 3a-h, esters 11,14, and thioester 17) in their N-alkyl side chain are studied.By irradiation fused hydropyrazines (4a, e, g, h) and hydro-1,4-diazepines (4b, f) were formed from amide derivatives 3 through photocyclization, whereas the esters 11,14 showed addition and reduction reactions of the imide carbonyl group, and thioester 17 showed Norrish-type I reaction of the thioester moiety, in each case, however, without yielding cyclized products.
