C-Acylimines 1 undergo intermolecular amidation with amides 2 to produce monoacyl gem-diamino acid derivatives 3 upon treatment with Cu(OTf)2 (20 mol %)/ PPh3 (20 mol %) under mild conditions. This method provides an efficient access to gem-diamino acid equivalents with good to excellent yields.
在温和的条件下,用Cu(OTf)2(20 mol%)/ PPh 3(20 mol%)处理后,C- Acylimines 1与酰胺2进行分子间酰胺化反应,生成单酰基宝石-二
氨基酸衍
生物3。该方法提供了以良好至优异的产率有效获得宝石-二
氨基酸等同物的方法。
