Palladium-diamine complexes catalyzed kinetic resolution of axially chiral 2,2'-dihydroxy-1,1'-biaryls by alcoholysis of vinyl ethers. The reaction proceeded with high selectivity for various kinds of biaryls. This process is applicable to not only binaphthols but also biphenols, which have been considered to be difficult for the enantioselective synthesis by known catalytic methods.
钯-二胺配合物通过乙烯基醚的醇解催化轴向手性 2,2'-二羟基-1,1'-联芳基的动力学拆分。该反应对各种联芳基具有高选择性。该方法不仅适用于联萘酚,也适用于联苯酚,它们被认为难以通过已知的催化方法进行对映选择性合成。
