A novel palladium-catalyzed intramolecular reductive amination of ketones with weakly nucleophilic sulfonamides has been developed in the presence of a Brønsted acid, giving a wide range of chiral γ-, δ-, and ε-sultams in high yields and up to 99% of enantioselectivity.
在布朗斯特酸存在下,已开发出一种新型钯催化的酮与弱亲核性磺酰胺的分子内还原胺化反应,可高产率地得到多种手性γ-、δ-和ε-磺内酰胺,对映选择性高达99%。
