Herein, we describe a method for the synthesis of aryl-(het)aryl ketones by Rh(III)-catalyzed direct coupling between quinoline-8-carbaldehydes and (het)arylboronic acids. The method has a broad substrate scope, a high functional group tolerance, and uses commercially available starting materials. Scale-up of the reaction and subsequent synthesis of tubulin polymerization inhibitor demonstrated its
在这里,我们描述了一种通过Rh(III)催化的喹啉8-甲醛与(杂)芳基硼酸之间的直接偶联合成芳基-(杂)芳基酮的方法。该方法具有广泛的底物范围,高的官能团耐受性,并使用可商购的起始原料。反应的放大和随后的微管蛋白聚合抑制剂的合成证明了其实用性。基于可以使用稳定的环酰基铑中间体配合物作为催化剂,并且该配合物与(杂)芳基硼酸化学计量反应的事实,提出了一种合理的机理。
