A series of novel Mannich bases with trifluoromethyl-1,2,4-triazole and substituted benzylpiperazine moieties were synthesized. Their structures were confirmed by IR, 1H NMR and elemental analysis. The single crystal structure of compound 4r was also determined. The preliminary bioassays showed that most of the lead compounds had low herbicidal activity against Brassica campestris, Echinochloa crusgalli, and KARI enzyme. However, most of them exhibited significant fungicidal activity at the dosage of 50μg/mL toward five test fungi. Among the 18 novel compounds, several showed superiority over the commercial fungicide Triadimefon against Cercospora arachidicola and Fusarium oxysporum f. sp. cucumerinum during this study. Meanwhile, some compounds displayed plant growth regulatory activity at the dosage of 10μg/mL.

experimental part, p. 5515 - 5522 (2011/08/03)
A series of trifluoromethyl-substituted 1,2,4-triazole Mannich base 6 and bis(1,2,4-triazole) Mannich base 7 containing pyrimidinylpiperazine rings via the Mannich reaction were synthesized and characterized by infrared (IR), 1H nuclear magnetic resonance (NMR), and elemental analysis. The fungicidal tests indicated that most of compounds 6 and 7 possessed excellent fungicidal activity. Among 19 novel compounds, some showed superiority over commercial fungicides Dimethomorph, Thiophanate-methyl, Iprodione, and Zhongshengmycin. Some compounds also exhibited favorable herbicidal activity in the preliminary studies. On the basis of the comparative molecular field analysis (CoMFA), five novel compounds were subsequently synthesized, their activities were estimated fairly accurately, and compounds 6-A1 and 7-A2 displayed good fungicidal activity against Pseudoperonospora cubensis (96.9 and 84.9%) as 6h and 7c, respectively.
