A series of novel thiazole acrylonitrile derivatives was designed and synthesized utilizing NC‐510 as a precursor. Their structures were characterized by NMR spectrometry, MS, and elemental analysis. The results of bioassay indicated that some of these title compounds exhibited 100% mortality at 50 mg/L against Aphis fabae. In particular, the compound 11c displayed the best activity: Its LC50 value
Using cyenopyrafen as the lead compound, a series of novelpyrazoleacrylonitrilecompounds were designed and synthesized via the reaction of butylphenylacetonitrile with the corresponding (substituted pyrazol‐5‐yl) methanone of pyrethroid alcohols in the presence of potassium tert‐butoxide. These compounds showed prominent acaricidalactivity against Tetranchus urticae. In particular, IIf, IIh, IIo
This invention relates to cysteine derivatives of the formula[I] and salts thereof. ##STR1## The compounds of this invention are useful for immunomodulator and treatment of liver disorder.
