An efficient access to cis -hydrobenzo[ b ]oxepine frameworks has been established through rhodium(I)-catalyzed cyclization of cyclohexadienone-tethered o -tolyl-substituted alkynes (1,6-enynes). The cascade process involves regioselective α-arylrhodation of the alkyne, 1,4-rhodium migration, and conjugate addition to cyclohexadienone.

有效获取顺式-氢苯并 [b] 氧杂环庚烷：铑（I）-催化环己二烯酮连接邻甲苯基取代炔烃的环化

通过铑（I）催化的环己二烯酮连接的邻甲苯基取代的炔烃（1,6-烯炔）的环化，已经建立了对顺式-氢苯并[b]氧杂环庚烷骨架的有效途径。级联过程涉及炔烃的区域选择性 α-芳基铑化、1,4-铑迁移和与环己二烯酮的共轭加成。
