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.
用重氮化合物或叠氮化钠处理3,(5)-(di)chloro-2 H -1,4-(benz)oxazin-2-ones生成双(三)环化合物,可将其转化为[1,2 ,3]三唑或1,5-二取代的四唑通过与亲核试剂(如甲醇,水和胺)反应。
