A palladium-catalyzed highly regioselective C–H allylation/annulation reaction of N-sulfonyl amides with secondary or tertiary allylic alcohols has been developed to construct 3,4-dihydroisoquinolones bearing a synthetically valuable vinyl substituent. This cascade cyclization approach of allylic alcohols involving C–H allylation has not been reported previously. The commercially available allylic
N-磺酰酰胺与仲或叔烯丙醇的钯催化高区域选择性 C-H 烯丙基化/环化反应已被开发出来,以构建具有合成价值的乙烯基取代基的 3,4-二氢异喹诺酮。这种涉及 C-H 烯丙基化的烯丙醇级联环化方法以前没有报道过。市售的烯丙醇底物(水的唯一副产品)和使用的末端氧化剂 O 2提供了环境友好的优势。

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.
