with 1 to 5-phenyl-1,2,4-triazolo[4,3-c]quinazoline-3-thiol which was readily converted into the corresponding alkylthio compounds by treatment with alkyl halides. Further, 4-(4-arylmethylene-5-oxo-2-phenyl-2-imidazolinylamino)-2-phenylquinazolines were obtained via the condensation of 4-arylmethylene-2-phenyl-2-oxazolin-5-ones with 1.
甲酸、乙酰基和苯甲酰氯在温和条件下用 2-苯基-4-喹唑啉基肼 (1) 处理,得到相应的酰肼,然后将其转化为 5-苯基 [1,2,4] 三唑并 [1,5-c]喹唑啉、2-甲基-5-苯基[1,2,4]三唑并[1,5-c]喹唑啉和2,5-二苯基[1,2,4]三唑并[1,5-c]喹唑啉(3a ) 分别通过加热超过它们的熔点。1 与醛反应产生相应的腙,在热解时产生相应的 [1,2,4] 三唑并 [1,5-c] 喹唑啉 (3a-i)。二硫化碳与 1 到 5-苯基-1,2,4-三唑并[4,3-c]喹唑啉-3-硫醇发生闭环,通过用卤代烷处理,很容易将其转化为相应的烷硫基化合物。更多,
