chiral α,α-diaryl carboxamides is developed by enantioselective cross-coupling between 2-bromo-2-aryl carboxamides and arylboronic acids, leading to a series of chiral α,α-diaryl carboxamides with various electronic properties and functionalities in moderate to excellent enantioselectivities and yields. The employment of a sterically bulky chiral P,P═O ligand L2 is critical for the reactivity and selectivity
通过2-溴-2-芳基羧酰胺与芳基硼酸之间的对映选择性交叉偶联,开发了一种手性α,α-二芳基羧酰胺的一般合成方法,从而产生了一系列具有各种电子性质和官能度的手性α,α-二芳基羧酰胺。中度至极好的对映选择性和产率。使用空间庞大的手性P,P = O配体L 2对于反应性和选择性至关重要。该协议适用于多巴胺受体激动剂SKF 38393关键中间体的有效不对称合成。
