The first application of α-d-galacturonic acid hydrate (GalA) is reported here, as a potential O-donor ligand. The C–N couplings of N-heterocycles with aryl halides or arylboronic acids could be readily conducted and exhibited good functional group tolerance with characters of selectivity. These N-arylazoles allow rapid access to several pharmaceutical intermediates and can be easily transformed into a variety of other interesting scaffolds as well.
这里报告了α-D-半乳糖醛酸水合物(GalA)作为潜在的O-供体配体的首次应用。N-杂环化合物与芳基卤化物或芳基硼酸的C-N偶联可以轻松进行,并且具有良好的官能团容忍性和选择性特征。这些N-芳基唑允许快速获得几种药用中间体,并且也可以轻松转化为各种其他有趣的骨架。
