An efficient method of selective -arylation of oxime ethers was realized by using a palladium catalyst with diaryliodonium salts as the key arylation reagents. The reaction proceeded smoothly through the activation of inert C(sp)-H bonds to give corresponding ketones and aldehydes. This convenient procedure can be successfully applied to construct new C(sp)-C(sp) bonds on a number of complex molecules derived from natural products and thus serves as a practical synthetic tool for direct late-stage C(sp)-H functionalization.
通过使用钯催化剂和二芳基碘鎓盐作为关键芳基化试剂,实现了一种肟醚的高效选择性芳基化方法。该反应通过惰性C(sp) - H键的活化顺利进行,生成相应的酮和醛。这一简便方法能够成功应用于在许多源自天然产物的复杂分子上构建新的C(sp) - C(sp)键,因此可作为直接后期C(sp) - H官能团化的实用合成工具。
