Acetone sensitized irradiation of novel 5,6-benzo-2-azabarrelenols were performed to afford di-?-methane photoproducts whose structures and ratios depended on the structural features and substituents; the phenyl substituent at C-8 rendered the pronounced effect on the formation of novel "cross-bonding" product through the imino-ether bridge, and importance of the product forming step for the observed regioselectivity was pointed out.
