Polysubstituted 2-oxopyrrolidines bearing at least two contiguous stereocenters constitute the core of several pharmaceuticals, including clausenamide (antidementia). Here, we describe a flexible annulation strategy, which unites succinic anhydride and 1,3-azadienes to produce allylic 2-oxopyrrolidines bearing contiguous stereocenters. The approach is chemoselective, efficient, modular, scalable, and
具有至少两个连续立体中心的多取代 2-氧代吡咯烷构成了多种药物的核心,包括黄皮酰胺(抗痴呆)。在这里,我们描述了一种灵活的成环策略,它将琥珀酸酐和1,3-氮杂二烯结合起来产生带有连续立构中心的烯丙基2-氧代吡咯烷。该方法具有化学选择性、高效、模块化、可扩展和非对映选择性。反应的可扩展性为后多样化提供了机会,导致具有已知药用价值或允许随后转化为医学相关实体的基序的结合。
