Synthesis of 5,7-Dimethyl-2-(5-Substituted-l,3,4-Oxadiazole-2-yl)-Methylenethio-1,2,4-Triazolo[1,5-a]Pyrimidines as Potential Fungicides
摘要:
A series of diheterocyclic compounds containing 1,2,4-triazolo [l,5-a]pyrimidine and 1,3,4-oxadiazole were designed and synthesized starting from 2-mercapto-5,7-dimethyl-l,2,4-triazolo [ 1,5-a] pyrimidine. The structure of all compounds prepared were confirmed by H NMR spectroscopy and elemental analysis. The preliminary bioassay indicated that the title compounds displayed good fungicidal activity against Rhizoctonia solani.
