Synthesis of new [1,2,3]triazoles and 1H-tetrazoles via reactions of 3,(5)-(Di)chloro-2H-1,4-(benz)oxazin-2-ones with diazocompounds or sodium azide

Treatment of 3,(5)-(di)chloro-2H-1,4-(benz)oxazin-2-ones with diazo compounds or sodium azide yields bi(tri)cyclic compounds which can be converted into [1,2,3]triazoles or 1,5-disubstituted tetrazoles via reactions with nucleophiles as methanol, water and amines.
