1,3‐Enynes containing allylic hydrogens cis to the alkyne function as three‐carbon components in rhodium(III)‐catalyzed, all‐carbon [3+3] oxidative annulations to produce spirodialins. The proposed mechanism of these reactions involves the alkenyl‐to‐allyl 1,4‐rhodium(III) migration.
含烯丙基氢的1,3-烯炔顺式延伸至炔烃,在铑(III)催化的全碳[3 + 3]氧化环中作为三碳组分生成螺二醛。这些反应的拟议机制涉及烯基至烯丙基1,4-铑(III)的迁移。
