- Synthesis and herbicidal activity of O,O-dialkyl(phenyl)-N-{1-[(6- chloropyridin-3-yl)methyl]-4-cyano-1H-1,2,3-triazol-5-yl}-1-amino-1- substitutedbenzyl-phosphonates
-
A series of novel -amino phosphonate derivatives containing both pyridine and 1,2,3-triazole moieties 4 were synthesized via a multi-step reaction. First, the condensation of 5-amino-1-[(6-chloropyridin-3-yl) methyl]-4-cyano-1H-1,2,3- triazole with various aromatic aldehydes in the presence of magnesium perchlorate afforded imines 3 in moderate yields; second, imines 3 reacted with dialkyl phosphites or triphenyl phosphite to give the title compounds 4 in moderate to good yields. Their structures were elucidated by spectroscopic data (IR, 1H NMR, 31P NMR, ESI-MS) and elemental analysis. The preliminary bioassay (in vitro) indicated that some of the title compounds 4 possessed moderate herbicidal activities against dicotyledonous plants (Brassica campestris L) at a concentration of 100 mg/L. However, compounds 4 did not exhibit herbicidal activities against Brassica campestris L at a concentration of 10 mg/L. Supplemental materials are available for this article.

- Synthesis and biological activities of O-(E)-(arylmethyl) 1-[1-(arylmethyl)-5-methyl-1H-1,2,3-triazol-4-yl] ethanone oxime ethers
-
(Chemical Equation Presented) A series of novel O-(E)-(arylmethyl) 1-[1-(arylmethyl)-5-methyl-1H-1,2,3-triazol-4-yl] ethanone oxime ethers were synthesized by the O-alkylation of 1-[1-(arylmethyl)-5-methyl-1H-1,2,3-triazol- 4-yl] ethanone oximes with various arylmethyl chlorides in the basic condition. Their structures were confirmed by IR, 1H NMR, mass spectroscopy, and elemental analyses. The preliminary bioassay indicated that some of the target compounds (4a-f) displayed good insecticidal and moderate fungicidal activity. For example, compounds 4c and 4g showed 100% and 90.6% death rates against aphides at the concentration of 250 mg/L, respectively, and compounds 4f and 4g displayed 67% and 78.4% inhibitory rates against Rhizoctonia solani at the dosage of 100 mg/L, respectively.
