A synthetic scheme extensively utilizing silylation-desilylation reactions to achieve the total synthesis of 2,6-substituted carbapenem antibiotics from readily available azetidinones is reported. An epimeric pair of new 2,6-substituted carbapenems, (±)-2-cyclopropyl-6-(1′-hydroxyethyl)-1-carbapen-2-em-3-carboxylic acids were synthesized.
报道了一种合成方案,该方案广泛地利用甲硅烷基化-去甲硅烷基化反应以从容易获得的氮杂环丁酮类化合物中完全合成2,6-取代的碳青霉烯类抗生素。合成了一对新的2,6-取代的碳青霉烯((±)-2-环丙基-6-(1'-羟乙基)-1-carbapen-2-em-3-羧酸)的差向异构对。
