This review represents the methods developed for the synthesis of a variety of nitrogen bridgehead heterocyclic systems such as [1,2,4]triazolo[1,5-a]pyridines, pyrido[1,2-b][1,2,4]triazines, pyrido[1,2-b][1,2,4]-triazepines, pyrazolo [1,5-b][1,2,4]triazole, pyrazolo[1,5-b][1,2,4]triazine, pyrazolo[1,5-b][1,2,4]triazepine, [1,2,4]triazolo [3,4-b] [1,2,4]triazine, [1,2,4]triazolo [4,3-b][1,2,4]triazepines, pyrimido[3,4-b][1,2,4]triazine from the heterocyclization of some heterocyclic diamines with a variety of electrophilic reagents.
