over the years, but they share common drawbacks in terms of generality and tolerability, especially to acid labile functionalities. Here we report a truncated Passerini reaction suitable for the easy and mild preparation of functionalized α-hydroxyamides. In particular, this procedure is tolerant to acid sensitive protecting groups, which remain intact during the multicomponent reaction.
多年来,已经描述了用于合成α-羟基酰胺的数十种策略,但是它们在通用性和耐受性(尤其是对酸不稳定的功能性)方面具有共同的缺点。在这里,我们报告截短的Passerini反应,适用于轻松温和地制备官能化的α-羟基酰胺。特别地,该方法耐受酸敏感性保护基,其在多组分反应期间保持完整。
