Cyclecondensation of 3-amino-1,2,4-triazole with substituted methyl cinnamates

Cyclecondensation of 3-amino-1,2,4-triazole with substituted methyl cinnamates

The reaction of 3‐amino‐1,2,4‐triazole (1) with substituted methyl cinnamates 2a‐h leads selectively to the formation of 7‐aryl‐6,7‐dihydro[1,2,4]triazolo[1,5‐a]pyrimidin‐5(4H)‐ones 3a‐h. The structure eluci dation of the products is based on ir, 1H and 13C nmr measurements and X‐ray diffraction....
