The first example of the palladium-catalyzed, three-component tandem reaction of 2-aminobenzonitriles, aldehydes, and arylboronic acids has been developed, providing a new approach for one-pot assembly of diverse quinazolines in moderate to good yields. A noteworthy feature of this method is the tolerance of bromo and iodo groups, which affords versatility for further synthetic manipulations. Preliminary
已经开发出了钯催化的2-氨基苄腈,醛和芳基硼酸的三组分串联反应的第一个例子,这为中度到良好收率的各种喹唑啉的一锅法组装提供了一种新方法。该方法的一个值得注意的特征是对溴和碘基的耐受性,为进一步的合成操作提供了多功能性。初步的机械实验表明,该串联过程涉及通过氰基的催化碳钯反应形成喹唑啉的两种可能的机械途径。
