An electrochemical method is presented to construct 1,3-oxazines by the oxidative ring-opening of cyclopropylamides with alcohols. This method avoids the use of external oxidants and thus shows good functional group tolerance. The substrate scope covers primary, secondary, and tertiary alcohols as well as (hetero)aryl amide-substituted cyclopropanes.
提出了一种通过环丙酰胺与醇的氧化开环构建 1,3-恶嗪的电化学方法。该方法避免了外部氧化剂的使用,因此表现出良好的官能团耐受性。底物范围涵盖伯醇、仲醇和叔醇以及(杂)芳基酰胺取代的环丙烷。
