A new synthetic route for the access to [1,2,3]triazolo[1,5-a][1,4]benzodiazepines and other derivatives is described. This strategy is based on the cycloaddition of 2-oxoalkylidenephosphoranes to o-functionalized aryl azides followed by the reaction of the corresponding triazole intermediate with amines. This new approach presents unique properties such as regioselectivity, modularity, mild reaction
描述了获得[1,2,3]三唑并[1,5- a ] [1,4]苯并二氮杂和其他衍生物的新合成途径。该策略基于将2-氧代亚烷基亚膦酰基环酮加成至o-官能化的芳基叠氮化物,然后使相应的三唑中间体与胺反应。这种新方法具有独特的性质,例如区域选择性,模块性,温和的反应条件和高收率。
