An efficient and mild one-pot approach for copper-catalyzed aerobic oxidative coupling of α-carbonyl aldehydes with terminal alkynes toward ynediones has been developed. Moreover, a variety of ynediones were constructed under the optimized reaction conditions, and a plausible mechanism was presented based on a series of control experiments.
已开发出一种高效温和的一锅法,用于铜催化α-羰基醛与末端炔烃向乙二酮的需氧氧化偶联。此外,在优化的反应条件下构建了多种二炔,并基于一系列对照实验提出了合理的机理。
