directly affords carbapen-2-ems, allowing a facile entry into a ring system previously accessible only by total synthesis, lengthly semisynthesis or fermentation. The chirality of the cephalosporin is accurately translated into the corresponding carbapenem. The resulting 1-oxocarbapenems (2) were selectively transformed through reduction into 1-oxygenated carbapenems and carbapenams (3 and 4, respectively)
容易获得的2-二氮杂3 -em氧化物的照片“沃尔夫”重排(1)直接提供了carbapen-2-em,使它们容易进入以前只能通过全合成,半合成或发酵才能获得的环系统。头孢菌素的手性可准确翻译为相应的碳青霉烯。通过还原将生成的1-氧代碳青霉烯(2)选择性转化为1-氧化的碳青霉烯和碳青霉烯(分别为3和4)。经微生物筛选,发现碳青霉烯(3c)具有广泛的活性。发现了一个有趣的抗菌素,用于碳青霉烯(26)。
