Abstract Carboxylic acids are conveniently and efficiently protected as their p-methoxybenzyl esters under very mild conditions using the pre-formed reagent N,N-diisopropyl-O-(4-methoxybenzyl)isourea, and this method allows selective protection of carboxylic acids in the presence of other functionalities such as enolisable ketones and alcohol groups.
摘要 在非常温和的条件下,使用预先形成的试剂 N,N-二异丙基-O-(4-甲氧基苄基)异脲可以方便有效地将羧酸作为对甲氧基苄酯进行保护,并且该方法可以选择性地保护羧酸中的羧酸。其他官能团的存在,例如可烯醇化的酮和醇基团。
