A one-pot cross double-Mannich reaction of acetaldehyde was developed, and densely functionalized 1,3-diamines were obtained as a single stereoisomer by use of axially chiral amino sulfonamide (S)-1 as catalyst. Using this catalyst, the one-pot Mannich reaction–aminoxylation was also realized.
开发了一种包含醛的单锅交叉双Mannich反应,通过使用轴向手性的氨基磺酰胺催化剂(S)-1,获得了作为单一立体异构体的高密度功能化1,3-二胺。此外,利用该催化剂还实现了一锅法的Mannich反应和氨基氧化反应。
