Benzodiazepines show a broad spectrum of biological activities. In an ongoing effort to extend molecular diversity in this type of systems, we developed a strategy for synthesizing 3,4-dihydro-1H-pyrido[2,3-e][1,4] diazepine-2,5-dione compounds starting from 2-hydroxynicotinic acid and by using an Ugi reaction as a key step in the synthesis. We opted to use 2isocyanophenyl benzoate instead of Armstrong's convertible isocyanide in this multicomponent reaction.
