faster than the commonly used methods which use NaH in THF or DMF for p-methoxybenzylation of hydroxy and amide groups. The described method was applicable for sterically hindered substrates at room temperature without adding any activating reagents such as tetrabutylammonium iodide.

氯利用的NaO吨-Bu在
DMSO中描述。在
DMSO中使用NaO t -Bu对位阻薄荷醇进行对甲氧基苄基化的过程比在THF或
DMF中使用NaH对羟基和酰胺基进行对甲氧基苄基化的常用方法进行得更快。所描述的方法适用于室温下受阻的底物,而无需添加任何活化剂,例如
四丁基碘化铵。
