We report the highly efficient gold-catalyzed hydrocarboxylation of internal alkynes that operates under solvent- and silver-free conditions. This new, simple, and eco-friendly protocol allows for the synthesis of a wide variety of functionalized aryl and alkyl enol esters in high yields, with Z-stereospecificity and good regioselectivities and without the requirement for purification by chromatography
我们报告了在无溶剂和无银条件下运行的内部炔烃的高效金催化加氢羧化反应。这种新的,简单且环保的方案允许以Z-立体特异性和良好的区域选择性高收率合成多种功能化的芳基和烷基烯醇酯,而无需通过色谱纯化。该方法代表用于合成烯醇酯的方便,操作上简单的方法。
