The present invention provides novel compositions of matter and processes for their preparation. Particularly, the present invention relates to novel monocyclic β-lactams of formula I, having a carbonyl group, other than a negatively charged group, attached to the N-1 position. The compounds are useful as antimicrobial agents or as intermediates thereto. The present invention also provides a novel process for making these compounds which utilizes palladium (O)-catalyzed carbonylation of an appropriate 2-bromo-1-propen-3-yl amine and novel intermediates prepared by this process.
本发明提供了一种新的物质组合物及其制备过程。特别是,本发明涉及一类新型的单环β-内
酰胺类化合物,其具有一个羰基团,而不是一个负电荷团,连接到N-1位置。这些化合物可用作抗菌剂或作为其前体。本发明还提供了一种制造这些化合物的新过程,该过程使用
钯(0)催化的2-
溴-
1-丙烯-3-基胺的羰基化反应,以及通过该过程制备的新型中间体。
