The protection of a wide variety of alcohols as their p-methoxybenzyl ethers can be performed with PMBO-lepidine in the presence of methyl tosylate or, preferably, camphorsulfonic acid. No inorganic promoters are required, thereby facilitating workup and product isolation.
使用PMBO-邻二氮菲和甲基对甲苯磺酸酯或更优选樟脑磺酸,可以在不使用无机促进剂的情况下,保护多种醇生成其对甲氧基苄基醚,从而简化了工作流程和产物分离。
