report an enantioselective palladium‐catalyzed cross‐coupling between α‐bromo carboxamides and aryl boronic acids, generating a series of chiral α‐aryl carboxamides in good yields and excellent enantioselectivities. The development of a chiral P,P=O ligand was critical in overcoming the second transmetalation issue and allows the first asymmetric palladium‐catalyzed coupling of α‐bromo carbonyl compounds
我们在本文中报道了α-溴羧酰胺与芳基硼酸之间的对映选择性钯催化的交叉偶联,以高收率和优异的对映选择性产生了一系列手性α-芳基羧酰胺。手性P,P = O配体的发展对于克服第二个金属转移问题至关重要,并且可以实现α-溴代羰基化合物的第一个不对称钯催化偶联。
