We present α-chloro amides as a new class of α-acetyl radical precursors, which undergo a tin-free, photoredox-catalysed intermolecular α-alkylation with various olefins exclusively in an anti-Markovnikov fashion. The reaction represents a reductive atom transfer radical addition (ATRA) and provides a series of alkylated amides in good yields.
我们提出了α-氯酰胺作为一种新的α-乙酰基自由基前驱体,它可以与各种烯烃进行无锡锡的光催化 intermolecular α-烷基化,且反应完全遵循反马尔科夫尼科夫规律。该反应代表了一种还原性原子转移自由基加成(ATRA),并且提供了一系列高产率的烷基化酰胺。
