Upon irradiation a regio- and stereoselective cycloaddition occurred intramolecularly between two acyl-1,4-benzoquinone moieties connected by a polymethylene bridge. The regio- and stereoselectivities are different from those of the corresponding intermolecular cycloaddition; this was interpreted in terms of the Diels-Alder reaction between an acyl-1,4-benzoquinone moiety and a photochemically produced
辐照后,通过聚亚甲基桥连接的两个酰基-1,4-苯醌部分之间发生分子内的区域和立体选择性环加成。区域和立体选择性与相应的分子间环加成不同;这被解释为酰基-1,4-苯醌部分和光化学产生的二烯醇之间的狄尔斯-阿尔德反应。
