A protocol for the synthesis of α,β‐unsaturated aldehydes and allylic alcohols from simple allylic hydrocarbons with water via palladium‐catalyzed functionalization of allylic C−H bonds was described. Molecular oxygen is utilized as the sole oxidant in this oxygenation of terminal alkenes. This protocol features good functional group compatibility, broad substrate scope, and high atom‐ and step‐economy
描述了通过钯催化的烯丙基CH键的官能化,由简单的烯丙基烃与水合成α,β-不饱和醛和烯丙基醇的方案。在末端烯烃的这种氧化中,分子氧被用作唯一的氧化剂。该协议具有良好的官能团兼容性,广泛的底物范围以及高原子经济性和阶梯经济性。而且,该方法在合成布洛芬中的应用可以突出该方法的合成效用,布洛芬是一种非常有效的止痛药。
