The synthesis of polyfunctionalised enantiopure 1,4-diazepan-3-one scaffolds from l-serine derivatives and azidoepoxides readily available from either l-ascorbic or d-isoascorbic acid, allowing access to various configurations at chiral centres, is described. The key steps are the nucleophilic opening of the epoxide by the amine of serine followed by a lactonisation–lactamisation sequence.
描述了从l-丝氨酸衍生物和叠氮环氧化物容易地从l-抗坏血酸或d-异抗坏血酸获得的多官能化对映体纯的1,4-二氮杂-3-酮骨架的合成,其允许在手性中心获得各种构型。关键步骤是丝氨酸的胺向环氧化物的亲核打开,然后进行内酯化-内酰胺化序列。
