[reaction: see text] A strategy for the synthesis of the spirocyclic core of spirolucidine was explored through a model study. The diene 4a was prepared and photolyzed to give the desired [2 + 2] photoadduct 17 containing the correct relative stereochemistry corresponding to spirolucidine.
[反应：见正文] 通过模型研究探索了一种合成螺卢西定螺环核心的策略。制备了二烯4a并进行光解，得到所需的[2 + 2]光环化加成物17，其具有与螺卢西定相对应的正确相对立体化学结构。
