Copper-catalyzed oxidative coupling between quinazoline 3-oxides and unactivated aldehydes: an efficient approach to functionalized quinazolines†
Abstract
A copper-catalyzed oxidative coupling between quinazoline 3-oxides and unactivated aldehydes was described. The reaction worked well for both aliphatic and aromatic aldehydes and produced not only the direct oxidative coupling ketones but also cyclic hydroxamic esters derived from quinazolines.
