An efficient one‐pot synthesis of hydroxamic acids from aldehydes and hydroxylamine is described. A fast, visible‐light‐mediated metal‐free hydroacylation of dialkyl azodicarboxylates was used to develop the subsequent addition of hydroxylamine hydrochloride. A range of aliphatic and aromatic aldehydes were employed in this reaction to give hydroxamic acids in high to excellent yields. Application
描述了一种有效的一锅法从醛和羟胺合成异羟肟酸的方法。快速,可见光介导的偶氮二羧酸二烷基酯的无金属加氢酰化反应用于随后添加盐酸羟胺的过程。在该反应中使用了一系列脂族和芳族醛,以高产率或优异产率得到异羟肟酸。在抗癌药伏立诺他的合成中证明了当前方法的应用。
