Functionalised azepane and oxepane scaffolds were prepared using diazocarbonyl chemistry and elaborated to show their potential use in library synthesis. Key dicarbonyl containing seven-membered rings were functionalised via diastereoselective Luche reduction of the ketone followed by manipulation of the ester and amine groups. Further scaffolds could be accessed by C-alkylation of the dicarbonyl compounds. In addition, an oxepane containing amino acid could be prepared via a diastereoselective enamine reduction.
