A total of 15 novel-substituted 3-(benzylsulfanyl)-1H-1,2,4-triazol-5-ylamines I [R = 3-MeC6H4, 2-FC6H4, 2,4-Cl2C6H3, etc.] and 10 novel-substituted 3-benzylmercapto-1,2,4-triazole derivatives II were synthesized based on the natural product phenazine-1-carboxylic acid (PCA). Their structures were confirmed by 1H-NMR, 13C-NMR, HRMS and X-ray. Most substituted 3-benzylmercapto-1,2,4-triazole derivatives II displayed very strong fungicidal activity against one or multiple plant pathogens in vitro and in vivo. Compounds II [R = 4-MeC6H4, 4-iPrC6H4, 4-tBuC6H4, etc.] showed a broad spectrum of fungicidal activity. Further field experiments indicated that compounds II [R = 4-MeC6H4, 2-FC6H4, 4-iPrC6H4, etc.] displayed better efficacy against rice blast (Pyricularia oryzae) than PCA. These data demonstrated that compounds II [R = 4-MeC6H4, 2-FC6H4, 4-iPrC6H4, etc.] were promising fungicidal candidates, deserving further studies. The experimental process involved the reaction of 3-Chlorobenzylchloride(cas: 620-20-2Category: chlorides-buliding-blocks)
3-Chlorobenzylchloride(cas: 620-20-2) has been used in the reaction of 3-methoxybenzyl chloride and ethyl 4-bromobenzoate in pure water, using zinc dust and a Pd catalyst.Category: chlorides-buliding-blocks
