| Abstract: | reaction: see text] UV irradiation of alkoxy-substituted N-alkenylmaleimides induces a sequence involving a 5 + 2] cycloaddition followed by a Norrish-Yang cyclization. The resulting highly strained alkylidene oxetanol-fused azepines are formed in good yield and with high diastereoselectivities |
