practical and flexible strategy toward α-hydroxy-β-amino esters and amides, which are important biological motifs, based on an organocatalytic cross-aldol reaction of in situ-generated nitrosocarbonyl intermediates followed by hydrogenation is presented. The protocol features operational simplicity, high yields, a wide substrate scope, and high regio- and diastereoselectivity profiles. The utility of
基于原位生成的亚硝基羰基中间体的有机催化交叉羟醛反应,然后氢化,提出了一种重要的生物学基序-α-羟基-β-氨基酯和酰胺的实用且灵活的策略。该协议具有操作简便,产率高,底物范围广,区域选择性和非对映选择性高的特点。通过Bestest类似物的合成和吲哚的形成展示了该方法的实用性。
