Synthesis of carbon-14 labeled ZJ0712, a novel strobilurin fungicide.

ZJ0712, a broad-spectrum fungicidal ingredient of strobilurin, exhibits a high protective and curative activity against plant pathogenic fungi. To support the study on its metabolism, residue, environmental behavior, and fate for safety evaluation, two versions of carbon-14 labeled ZJ0712, methyl (E)-2-(2-((2,5-dimethylphenoxy)methyl)phenyl)-3-methoxy[2-14 C]acrylate (2) and methyl (E)-2-(2-((2,5-dimethyl[phenyl-U-14 C6 ]phenoxy)methyl)phenyl)-3-methoxyacrylate (3), were synthesized from barium [14 C]carbonate in 6-step yield of 47% and from 2,5-dimethyl[phenyl-U-14 C6 ]phenol in the yield of 91%, respectively.
