Upon irradiation, thiohomophthalimides with an alkenyl group in their N-side chain or at the benzylic position give tricyclic isoquinoline derivatives through regioselective intramolecular [2+2] cycloaddition or Norrish type II reaction, respectively, in good yields.
辐射后,在其N侧链或苄基位置带有烯基的硫代邻苯二甲酰亚胺分别通过区域选择性分子内[2 + 2]环加成反应或Norrish II型反应生成三环异喹啉衍生物,收率很高。
