摘要

我们报告了邻羟基芳烯丙基胺与受体-受体重氮化合物的光催化烷基化反应，从而获得 3-烷基色酮。该反应涉及通过光敏剂的能量转移对重氮底物进行三重敏化。该方案的显著特点是操作简单、底物范围广、产物产量普遍较高。

Synthesis of 3-Substituted Chromones through Photoactivation of Acceptor–Acceptor Diazo Compounds

We report the photocatalytic alkylation of o-hydroxyarylenaminones with acceptor–acceptor diazo compounds to access 3-alkyl chromones. The reaction involves triplet sensitization of the diazo substrate via energy transfer from the photosensitizer. The notable features of the protocol are operational simplicity, wide substrate scope, and generally high yields of the products.
