We present a novel synthetic method for oxamate esters using bromodifluoroacetate esters and amines under aerobic photoredox catalysis. In contrast to previous methods that require the use of moisture-sensitive precursors and/or harsh conditions, this method utilizes bench-stable bromodifluoroacetate esters as an oxamate ester precursor under mild conditions, providing a variety of oxamate esters.

有氧光氧化还原催化溴二氟乙酸酯合成草酸酯

我们提出了一种在有氧光氧化还原催化下使用溴二氟乙酸酯和胺合成草酸酯的新方法。与之前需要使用湿敏前体和/或苛刻条件的方法相比，该方法在温和条件下利用实验室稳定的溴二氟乙酸酯作为草酸酯前体，提供多种草酸酯。
