Cyclization of the compounds with benzylic R 2 was successful and both electronwithdrawing (-F, -CF3) and electron-donating (-CH3) substituents of this benzyl moiety were well-tolerated in the photoreaction, giving the desired products 17b-17f in yields ranging from 69% to 79%. The only exception occured for R 2 = p-NO2-Bn, where the cyclization did not yield the desired product and the starting material could be regained.
