2-Iodocyclopentenones undergo a Heck reaction with allylic and homoallylic alcohols, in acceptable yields, to give dicarbonyl compounds useful for the construction of annulated cyclopentanones. In contrast, the corresponding iodo-substituted cyclohexenones, cycloheptenones and acyclic α,β-unsaturated ketones are far less or even unsuitable for Heck reactions of this type.
2-碘代环戊烯酮与烯丙醇和高烯丙醇以可接受的产率发生 Heck 反应,得到可用于构建环状环戊酮的二羰基化合物。相比之下,相应的碘取代的环己烯酮、环庚烯酮和无环的α,β-不饱和酮则很少甚至不适合这种类型的Heck反应。
