demethylation, debenzylation, and deallylation of aryl ethers using HPPh2 and tBuOK is reported. The reaction features mild and metal-free reaction conditions, broad substrate scope, good functional group compatibility, and high chemical selectivity towards aryl ethers over aliphatic structures. Notably, this approach is competent to selectively deprotect the allyl or benzyl group, making it a general and practical
报道了使用 HPPh 2和t BuOK 对芳基醚进行去甲基化、去苄基化和去烯丙基化的通用方法。该反应具有温和且不含金属的反应条件、广泛的底物范围、良好的官能团相容性以及对芳基醚的化学选择性高于脂肪族结构。值得注意的是,这种方法能够选择性地去保护烯丙基或苄基,使其成为有机合成中通用且实用的方法。
