amines. Employing a simple copper(I)/Nb6O19} catalyst system, the reaction offers a facile process to give functionalized α-ketoamides from readily available arylacetic acids under aerobic conditions. The merit of this new strategy is that it expands the syntheses of α-ketoamides from stable, inexpensive and widely available acylation reagents such as arylacetic acids in one step.
本文描述的方法是从芳族丙烯酸和胺合成α-酮酰胺的通用,有效和绿色方法。采用简单的铜(I)/ Nb 6 O 19 }催化剂体系,该反应提供了一种容易的方法,可以在好氧条件下从容易获得的芳酸中得到官能化的α-酮酰胺。这种新策略的优点在于,它一步一步就可以从稳定,廉价且广泛使用的酰化试剂(例如芳基乙酸)中扩展α-酮酰胺的合成。
