activated alcohol derivatives is desirable, as alcohols can be utilized in various radical-mediated reactions. Herein, we introduce α-N-phthalimido-oxy isobutyrate (NPIB) as a novel activating group for alcohols. Essentially, it is a more chemically robust alternative to Overman’s N-phthalimidoyl oxalate group. The utility of the NPIB group is showcased in the conversion of tertiary alcohols to nitriles
通过 SET 介导的活化醇衍生物脱氧生成自由基中间体是理想的,因为醇可用于各种自由基介导的反应。在这里,我们引入α- N-邻苯二甲酰亚胺氧基异丁酸酯(NPIB)作为一种新型的醇活化基团。从本质上讲,它是 Overman 的N-邻苯二甲酰亚氨基草酸酯基团的化学稳定性更强的替代品。 NPIB 基团的实用性体现在在 Ir/Cu 双催化剂下以及在 TMSCN 存在下在蓝色 LED 照射下将叔醇转化为腈。借助我们新开发的 NPIB 手柄,衍生自羧酸的N-羟基邻苯二甲酰亚胺酯的反应活性可以通过天然和商业上更丰富的醇底物实现。
