A facile selective method has been developed for the synthesis of new fluorine-containing cispentacin stereoisomers. Mono- and difluorinated cispentacin derivatives were synthetized from a bicyclic β-lactam in five or six steps involving a regio- and stereoselective hydroxylation through iodooxazoline formation, followed by deoxygenation by fluorination. Starting from an enantiomerically pure bicyclic
已经开发了一种简便的选择性方法来合成新的含氟顺五霉素立体异构体。单氟化和二氟化顺喷菌素衍生物是由双环 β-内酰胺以五或六个步骤合成的,包括通过碘恶唑啉形成的区域和立体选择性羟基化,然后通过氟化脱氧。从通过外消旋化合物的酶促拆分获得的对映异构纯双环 β-内酰胺开始,对映发散程序允许制备右旋和左旋二氟化顺喷菌素。
