efficient entry into cis monobactams starting from β -hydroxyesters is reported. This preparation is based on the stereoselective “electrophilic amination” of β-hydroxyester dianions and on Miller's biomimetic synthesis of the β-lactam nucleus. By this route, key intermediates for the preparation of pharmacologically important cis aztreonam 2 and carumonam 3 were prepared.
据报道,从β-羟基酯开始新的有效进入顺式单bactams的方法。该制备基于β-羟基酯二价阴离子的立体选择性“亲电胺化”和β-内酰胺核的米勒仿生合成。通过这种途径,制备了用于制备具有药理学意义的顺式氨曲南2和卡鲁米南3的关键中间体。
