chain, are described. The introduction of a methyl substituent at the C-1 position was accomplished by a newly developed procedure using crotyl halides and zinc dust. The 2-hydroxymethyl carbapenems as key intermediates allowed an easy entry into the preparation of title carbapenems.
描述了具有6-[((R)-1-羟乙基)侧链的1-甲基卡宾烯,2-杂芳族硫代甲基和2-氨基甲酰氧基甲基衍生物的合成和抗菌活性。通过使用巴豆基卤化物和锌粉的新开发的方法完成在C-1位上的甲基取代基的引入。以2-羟甲基碳青霉烯为主要中间体,可以轻松地制备标题碳青霉烯。
