Use of conformational constraints, induced by different ortho-substituents in 1-allyloxy-2-(substituted)methylbenzenes, where the substituent is a 1,3-dipole such as the azide or 3-oxidopyridinium group, can be employed to accelerate the 1,3-dipolar cycloaddition reaction. In this manner cycloadditions that otherwise do not proceed can be forced to react.
可以采用由1-烯丙氧基-2-(取代)甲基苯中不同邻位取代基引起的构象约束条件(其中取代基为1,3偶极子,如叠氮化物或3-氧化吡啶鎓基团)来加速1 ,3-偶极环加成反应。以这种方式,否则将不进行的环加成反应可以被迫进行反应。
