We present a new paradigm for nitroxyl-mediated processes via the merger of oxoammonium cation-mediated oxidation with visible-light photoredox catalysis. The integration of these two forms of catalysis has been realised for the oxidative amidation of aldehydes, furnishing N-acylated heterocycles. Extension of this process to the oxidative amidation of alcohols via the intermediacy of an aldehyde was successfully pursued, thus proffering a general oxidation platform. The activated amides synthesised here are excellent synthetic handles for acylation.

醇和醛氧化官能经由含氧铵阳离子和photoredox催化的合并

我们通过氧铵阳离子介导的氧化与可见光光氧化还原催化的合并，提出了一种新的硝化介导过程范式。对于醛的氧化酰胺化，提供了N-酰化的杂环，已经实现了这两种催化形式的整合。已成功地寻求通过醛的中间体将该方法扩展至醇的氧化酰胺化，从而提供了通用的氧化平台。此处合成的活化酰胺是酰化的出色合成方法。
