rearrangement, a wide range of aromatic amides react smoothly with arylboron reagents, affording a series of biologically relevant diarylmethylamines as deoxygenative C−C bond cross-coupling products. With its simplicity and versatility, this reaction shows great promise in the synthesis of amines from amides, which may open up new avenues in retrosynthetic planning and find widespread use in academia
在许多类型的化学转化中,酰胺本质上是惰性的羧基衍生物。特别是,由于共振稳定的酰胺 C=O 键的惰性,酰胺与合成重要胺的脱氧 C-C 键形成对合成化学家来说是一个长期存在的挑战。本文公开了通过将电子转移诱导的活化与 1,2-金属酸盐重排相结合,广泛的芳香酰胺与芳基硼试剂顺利反应,提供一系列生物学相关的二芳基甲胺作为脱氧 C-C 键交叉偶联产品。由于其简单性和多功能性,该反应在由酰胺合成胺方面显示出巨大的希望,这可能为逆合成规划开辟新的途径,并在学术界和工业界得到广泛应用。
