Reported herein is a photoredox-catalyzed amination of hydroxyarylenaminones with -butyl ((perfluoropyridin-4-yl)oxy)carbamate, a versatile amidyl-radical precursor developed in our laboratory. This work establishes a new cascade pathway for the assembly of a range of 3-aminochromones under mild conditions. Downstream transformations of the obtained 3-aminochromones to construct diverse amino pyrimidines greatly broaden the applications of this photocatalyzed protocol.
本文报道了一种光氧化还原催化的羟芳亚胺酮与我们实验室开发的多功能酰基自由基前体 - 丁基 ((全氟吡啶-4-基)氧基) 氨基甲酸酯的胺化反应。这项工作在温和条件下建立了一系列 3-氨基色酮的新型级联途径。获得的 3-氨基色酮的下游转化为构建各种氨基嘧啶极大地拓宽了该光催化方案的应用。
