A chemoselective reduction of N-hydroxyphthalimides to phthalimides under mild conditions has been discovered. It involves reaction of an N-hydroxyimide with bis(pinacolato)diboron in the presence of a base. Other easily reducible functional groups, such as iodo, nitro, or azido groups are unaffected. Alternatively, such functional groups may be selectively reduced without affecting the N-hydroxyimide moiety using a set of classical conditions.
发现了一种在温和条件下将 N-羟基邻苯二甲酰亚胺化学选择性还原为邻苯二甲酰亚胺的方法。它涉及 N-羟基亚胺与双(频哪醇)二硼在碱存在下的反应。其他易还原的官能团,如碘基、硝基或叠氮基均不受影响。另外,也可以使用一套经典条件选择性地还原这些官能团,而不影响 N-羟基亚胺分子。
