A convenient synthesis of α-hydroxy-β-lactams has been devised that involves the annelation of an inline with benzyloxyacetyl chloride and triethylamine and subsequent hydrogenolysis in the presence of palladium on carbon. In most cases a cis-β-lactam was obtained. A thioimidate can also be used as the imino component in the annelation reaction but the hydrogenolysis step fails. The annelation of the
已经设计了一种方便的α-羟基-β-内酰胺的合成方法,该方法包括用苄氧基乙酰氯和三乙胺使内联反应脱核,然后在钯/碳存在下进行氢解。在大多数情况下,获得了顺式-β-内酰胺。硫代亚氨酸酯也可以在成核反应中用作亚氨基组分,但是氢解步骤失败。适当的成环噻唑啉6-外延-penicillin衍生物与苄氧基乙酰氯比具有叠氮基乙酰氯发生容易得多。
