Abstract: A novel route for the preparation of 2H-1,4- benzoxazin-3(4H)one and 1,5 benzoxazepinones by intramolecular cyclization of N-hydroxy 2-phenoxyacetamide and N-hydroxy -3 phenoxypropanamide using PPA and Lewis acid has been discussed. Graphical abstract: [Figure not available: see fulltext. Caption: Preparation of 2H-1,4- benzoxazin-3(4H)one and 1,5 benzoxazepinones by electrophilic aromatic substitution from N-hydroxy 2-phenoxyacetamide and N-hydroxy -3 phenoxypropanamide and their acetyl and benzoyl derivatives using PPA and Lewis acids.]

Hydroxamates are valuable tools for chemical biology as well as interesting leads for medicinal chemistry. Although many hydroxamates display nanomolar activities against metalloproteases, only three hydroxamates have reached the market, among which is the HDAC inhibitor vorinostat. Failures in development are generally attributed to lack of selectivity, toxicity, or poor stability. To help medicinal chemists with respect to plasma stability, we have performed the first and preliminary study on structure-plasma stability for hydroxamates. We define some structural rules to predict or improve the plasma stability in the preclinical stage.
