报道了Ga(OTf)3催化邻苯二胺和酮的反应,高产率地得到了1,5-苯并二氮杂[艹卓],产物结构经核磁、质谱得到了证实.
Reaction of o-phenylenediamines and a wide range of substituted ketones could be effectively catalyzed by 10 mol% gallium triflate to give the corresponding 1,5-benzodiazepines in good to excellent isolated yields(70% - 92% )under mild conditions.
