A route to two epimeric hitherto unknown 2-piperidinylglycine derivatives, as precursors of carbocyclic β-lactam derivatives, has been developed, which features diastereoselective addition of allyl metal reagents to an N-allylimine derivative of Garner’s aldehyde and ring-closing metathesis as key steps.
已经开发出了两个迄今尚未公开的2-哌啶基甘氨酸衍生物作为碳环β-内酰胺衍生物的前体的途径,该途径的主要步骤是将烯丙基金属试剂非对映选择性地添加到加纳醛的N-烯丙胺衍生物上并进行闭环复分解。
