mediated by hypochlorite ion, which is formed in situ by reduction of sodium chlorite. The reaction conditions tolerate the presence of free hydroxyl groups and typical functional groups such as TBS, aryl, alkyl, allyl, acetyl, and benzyl groups; however, when an activated aromatic ring (e.g., sesamol) is present in the substrate, the use of a scavenger is necessary.
据报道,一种直接的方法是使用亚氯酸钠通过串联的C–H氧化/双键环氧化从叔烯丙胺制备2,3-环氧酰胺。显然,反应过程包括两个步骤:(i)用亚氯酸钠将起始烯丙胺烯丙基氧化为相应的不饱和烯丙基酰胺,然后(ii)由次氯酸根离子将烯丙基酰胺环氧化为2,3-环氧酰胺,形成通过还原亚氯酸钠就地还原。反应条件容许存在游离羟基和典型的官能团,例如TBS,芳基,烷基,烯丙基,乙酰基和苄基;然而,当基质中存在活化的芳环(例如芝麻酚)时,必须使用清除剂。
