direct oxidation of unprotected amino alcohols to their corresponding amino carbonyl compounds has often posed serious challenges in organic synthesis and has constrained chemists to adopting an indirect route, such as a protection/deprotection strategy, to attain their goal. Described herein is a highly chemoselective aerobic oxidation of unprotected amino alcohols to their amino carbonyl compounds
未保护的氨基醇直接氧化成其相应的氨基羰基化合物经常在有机合成中面临严峻挑战,并限制了化学家采用间接路线(例如保护/脱保护策略)来实现其目标。本文描述了未保护的氨基醇对它们的氨基羰基化合物的高度化学选择性好氧氧化,其中使用了2-氮杂金刚烷N-氧基(AZADO)/铜催化。所开发的催化系统导致带有伯,仲或叔氨基的各种未保护氨基醇的醇选择性氧化,在环境温度下暴露于空气下具有良好至高收率,从而为合成氮提供了灵活性。含有化合物。
