在这里，我们报告了一种简单的一步合成新的刚性N，O-杯芳烃配体的方法，这种方法是基于铜催化的下边胺化反应。我们还介绍了这些配体与一些主要基团和过渡金属的配位性质，与文献中报道的杯芳烃金属配合物相比，在几个有机转化中得到了具有优异催化活性的新的配合物。
Here, we report a simple one-step access to new rigid N,O-calixarene ligands which is based on copper-catalyzed amination at the lower rim. We also present the coordination properties of these ligands with some main group and transition metals leading to new complexes with superior catalytic activity, in several organic transformations, compared with calixarene metal complexes reported in the literature.
