for promoting oxidation of amines in aqueous-organic medium was developed. NaIO4 and TEMPO as the catalyst emerged as the most efficient and selective system for oxidation of differently substituted benzyl amines to the corresponding benzaldehydes without overoxidation. Unsymmetrical secondary amines underwent selectiveoxidation only at the benzylic position thus realising an oxidative deprotection
开发了一种新的无金属方案,用于促进水-有机介质中胺的氧化。 NaIO 4和 TEMPO 作为催化剂,成为将不同取代的苄胺氧化成相应苯甲醛且不发生过度氧化的最有效和选择性的系统。不对称仲胺仅在苄基位置进行选择性氧化,从而实现了苄基基团的氧化脱保护,并且易于胺回收。
