Synthesis and Biological Activities of Novel Thiophosphoryl Oximates Containing Thiazole and 1,2,3‐Triazole Rings

Abstract

AbstractIn order to find novel high activity and low toxicity agrochemicals, a series of novel thiophosphoryl oximates containing thiazole and 1,2,3‐triazole rings 4 were synthesized by the reactions of 1‐{1‐[(2‐chlorothiazol‐5‐ yl)methyl]‐5‐methyl‐1H‐1,2,3‐triazol‐4‐yl}ethanone oxime with various asymmetric thiophosphoryl chlorides. Their structures were confirmed by IR, 1H NMR, 31P NMR, EI‐MS and elemental analyses. The target compounds existed as E‐configuration, which was deduced by NMR analysis and by comparison with their pyridyl analog determined by X‐ray diffraction. The results of preliminary bioassay indicate that some of title compounds possess moderate insecticidal and fungicidal activities.
