Abstract
A new methodology for the synthesis of novel benzo[b][1,4]diazepine derivatives via a one-pot, multi-component reaction of benzaldehyde, o-phenylenediamine, and ethyl propiolate has been developed. Readily available starting materials, operationally simple, metal-free reaction conditions, simplicity of product isolation and good yields are key advantages of this methodology. The structure of the benzo[b][1,4]diazepines were confirmed by NMR, HRMS and XRD.
