Two new types of imidazole derivatives: N-(2-R1-5-R2-1H-imidazol-4-yl) thioureas 7a-g and N-(2-R1-5-R2-1H-imidazol-4-yl) formamides 8b,c,g were obtained in high yields by the hydrolytic degradation of 6-R1-8-R2-2-thioxo-2,3-dihydroimidazo[1,5-a]-1,3,5-triazin-4(1H)-ones 5a-g and 6-R1-8-R2-imidazo[1,5-a]-1,3,5-triazin-4(3H)-ones 6b,c,d, respectively. The tautomeric preferences of the new imidazoles were determined.
通过分别水解降解6-R1-8-R2-2-硫代-2,3-二氢咪唑并[1,5-a]-1,3,5-三嗪-4(1H)-酮5a-g和6-R1-8-R2-咪唑并[1,5-a]-1,3,5-三嗪-4(3H)-酮6b、c、d,以高收率得到了两种新型咪唑衍生物:N-(2-R1-5-R2-1H-咪唑-4-基)硫脲7a-g和N-(2-R1-5-R2-1H-咪唑-4-基)甲酰胺8b、c、g。测定了新型咪唑的互变异构偏好性。
