Abstract

In the first part of this review we shall describe some industrial applications of photoinduced heterocyclic syntheses via singlet oxygen and via free radicals. The second part is dealing with large bench-scale synthesis of 1,2-diazepines which are thence used as building stones for the synthesis of some new polyheterocyclic systems.
