Aryl-substituted allylic chlorides are accommodated by a self-assembled cage in such a restricted orientation that the internal reaction sites are shielded while the external ones are exposed. This non-covalent protection enhances terminal regioselectivity in the allylic substitution.
芳基取代的烯丙基氯化物在自组装笼中以一种受限的取向被容纳,使得内部的反应位点被屏蔽,而外部的反应位点则暴露出来。这种非共价保护增强了烯丙基取代反应的末端区域选择性。
