A general and facile synthetic method for β-fluoroenones from silyl enol ethers or ketones, with a copper–amine catalyst system, has been developed. The reaction proceeded by a tandem process of difluoroalkylation–hydrolysis–dehydrofluorination. This method is characterized by high yields, excellent Z/E ratios, a low-cost catalyst, and a broad substrate scope. The synthetic potential of β-fluoroenones
已经开发了一种通用且简便的合成方法,该方法由甲硅烷基烯醇醚或酮与铜-胺催化剂体系合成β-氟烯酮。该反应通过二氟烷基化-水解-脱氢氟化的串联过程进行。该方法的特点是高收率,优异的Z / E比,低成本的催化剂和广泛的底物范围。β-氟烯酮的合成潜力已通过各种复杂的有机氟分子的构建得到证明。
