在手性磷酸的作用下,实现了2-萘酚与邻羟基苯基取代对苯二酚的不对称共轭加成反应。重要的是,该反应具有很好的化学和区域选择性。此外,该方案的特点是催化剂负载量低,反应条件温和,能够以良好到高的产率生成不对称的三芳基甲烷,并且通常具有较高的对映选择性。在手性磷酸的作用下,实现了2-萘酚与邻羟基苯基取代对苯二酚的不对称共轭加成反应。
The enantioselective conjugate addition of 2-naphthols to ortho-hydroxyphenyl substituted para-quinone methides has been achieved with the aid of a chiral phosphoric acid. Importantly, the reaction took place with excellent chemo- and regioselectivities. In addition, the protocol features a low catalyst loading, mild reaction conditions, and enables the formation of unsymmetrical triarylmethanes in good to high yields with generally high enantioselectivities. The enantioselective conjugate addition of 2-naphthols to ortho-hydroxyphenyl substituted para-quinone methides has been achieved with the aid of a chiral phosphoric acid.
