摘要
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. (c) 2007 Elsevier Ltd. All rights reserved.
