Using a polymer-supported phosphine-mediated intramolecular aza-Wittig reaction in a key step of a reaction sequence a diverse library of benzodiazepine-quinazolinone alkaloids (Circumdatins) has been prepared using a novel modified Eguchi protocol. The multi-arrayed library generation strategy commenced from readily accessible benzodiazepinedione derivatives (and anthranilic acids) and all library members were purified by reverse phase preparative HPLC.
