for the synthesis of a range of heterocyclic templates. While there are many useful synthetic methods available to access these intermediates, there are still opportunities for the discovery of useful methodologies for their construction from novel starting materials. In this regard, we report on the discovery of a facile Pd-catalyzed Mizoroki–Heck coupling of ethyl 3-ethoxyacrylate with aryl and heteroaryl
众所周知,β-酮酸酯是用于合成一系列杂环模板的有用中间体。尽管有许多有用的合成方法可用于获得这些中间体,但仍然有机会从新型原料中发现有用的方法来构建它们。在这方面,我们报告了一种发现,该反应是3-乙氧基丙烯酸乙酯与芳基和杂芳基卤化物在钯的催化下易于催化的Pid催化的Mizoroki-Heck偶联反应,形成取代的烷氧基丙烯酸酯,可以水解形成新型的芳基和杂芳基β-酮酸酯。
