After the reaction was detected by TLC, the solvent was evaporated under reduced pressure, and water was added, and pH was adjusted to 5-6 with hydrochloric acid to precipitate a solid, which was filtered to give a white solid, and after drying, 2.3 g of the white solid was obtained. The yield was 92%.
1.25 g (0.005 mol) of 5a was dissolved in 10 ml of N, N-dimethylformamide, and 0.83 g of potassium carbonate was added thereto, and the mixture was stirred for 0.5 h, and 1.26 g of 6a was added in portions, then, the mixture was heated to 80° C., and stirred for 8 hours. After the reaction was detected by TLC, the reaction solution was poured into 50 ml of saturated brine, and extracted with three portions of ethyl acetate (100 ml) and dried. After desolvation, it was purified by column chromatography eluting with petroleum ether: ethyl acetate 1000:1˜1400 to yield 1.95 g of oily product.
1.78 g (0.01 mol) of 1c was dissolved in 15 ml of N,N-dimethylformamide, and 1.51 g of potassium carbonate was added thereto, and the mixture was stirred for 0.5 h. and 1.2 g of 2c was added dropwise thereto, then, the temperature was raised to 60° C., and the reaction was stirred for 4 hours. After the reaction was detected by TLC, the solvent was evaporated under reduced pressure, and water was added, and pH was adjusted to 5-6 with hydrochloric acid to precipitate a solid, which was filtered to give a white solid, and after drying, 2.2 g of the white solid was obtained. The yield was 86.9%.
1.3 g (0.005 mol) of 3c was dissolved in 10 ml of N,N-dimethylfomamide, and 0.83 g of potassium carbonate was added thereto, and the mixture was stirred for 0.5 and 1:45 g of 2b was added in portions, then, the mixture was heated to 80° C., and stirred for 8 hours. After the reaction was detected by TLC, the reaction solution was poured into 50 ml of saturated brine, and extracted with three portions of ethyl acetate (100 ml) and dried. After desolvation, it was purified by column chromatography eluting with petroleum ether: ethyl acetate 1000:1-300 to yield 1.86 g of oily product.
1.35 g (0.005 mol) of 1 b was dissolved in 10 ml of N,N-dimethylformamide, and 0.83 g of potassium carbonate was added thereto, and the mixture was stirred for 0.5 and 1:45 g of 2b was added in portions, then, the mixture was heated to 80° C., and stirred for 8 hours. After the reaction was detected by TLC, the reaction solution was poured into 50 ml of saturated brine, and extracted with three portions of ethyl acetate (100 ml) and dried. After desolvation, it was purified by column chromatography eluting with petroleum ether: ethyl acetate 1000:1˜300 to yield 1.92 g of oily product.
1.0 g (0.002 mol) of 1 b was dissolved in 30 ml of ethanol, and 0.85 g of a 40% aqueous solution of methylamine was added thereto, then the mixture was heated to reflux temperature and reacted, the reaction was stirred for 8 hours. After the reaction was detected by TLC and desolvation, it was purified by column chromatography eluting with petroleum ether: ethyl acetate 1000:1˜300 to yield 0.86 g of oily product.

The samples were inoculated by spraying, the inoculated samples were moved into artificial climate, and relative humidity was maintained at 60-70%, the temperature was maintained at 23° C., after about 10 days, grading investigation was carried out according to the morbidity of the blank control, control effect was calculated according to disease index.
Test results of living protection activity of partial compounds were as follows:
At a concentration of 200 ppm, compounds 10, 19, 128, 147, 163, 195, 210, 211, 212, 257, 258, 259, 401, 402, etc. had an effect of preventing powdery mildew by more than 80%; compounds 1, 9, 34, 35, 36, 49, 50, 51, 55, 67, 113, 114, 127, 128, 146, 177, 178, 179, 180, 191, 193, 194, 199, 271, etc. had an effect of preventing powdery mildew by 100%.
At a concentration of 100 ppm, compounds 1, 51, 36, 55, 113, 114, 258, 218, 194, 146, 147, 177, 178, 191 had an effect of preventing powdery mildew by more than 50%; compounds 9, 35, 49 50, 127, 195, 212, 271, etc. had an effect of preventing powdery mildew effect by more than 80%;
At a concentration of 50 ppm, compounds 9, 50, 127, etc. had an effect of preventing powdery mildew by more than 80%.
Experimental Methods were as Follows:
Spray method: the test target was Tetranychus cinnabarinus, that is, broad bean leaves inoculated with adults of Tetranychus cinnabarinus were placed under the spray treatment of Potter spray towers. After treatment, the Tetranychus cinnabarinus was placed in an observation room and cultured at 25˜27° C., and the results were investigated after 48 hours. The brush was used to touch the insect body, and the unresponsive were regarded as dead insects. The test concentrations of the compounds on killing cinnabarin were 50, 25, 12.5, 6.25, 3.125 mg/L.
Egg test: each treated broad bean leave was inoculated with 10 adults of Tetranychus cinnabarinus, and the adults were removed after the eggs were laid for 24 hours. The leaves with eggs were sprayed under Potter spray towers. After treatment, the eggs of Tetranychus cinnabarinus were placed in an observation room and cultured at 25˜27° C. And the test was examined until the eggs under the blank treatment completely hatched out. The concentration of the compound that kills the eggs of Tetranychus cinnabarinus was 100, 50, 25, 12.5, 6.25 mg/L.
Nymph test: broad bean leaves were inoculated with 10 adult mites, and the adults were removed after laying eggs for 24 hours. The eggs were fed in insect rearing room, and when they hatched into nymphs, they were sprayed with a sprayer. After treatment, the leaves with the nymphs were placed in an observation room and cultured at 25-27° C., and the results were investigated after 48 hours. A brush was used to touch the insect bodies, and the unresponsive were regarded as the dead. The test concentrations of the compound on killing cinnabarin were 5, 2.5, 1.25, 0.625, 0.3125 mg/L.
The comparison test results were as follows:
In the cases where compound 67 and fluacrypyrim were given at a concentration of 50, 25, and 12.5 mg/L, respectively, the lethal rate of compound 67 against adult mites was better than that of fluacrypyrim.
In the cases where compound 67 and fluacrypyrim were given at a concentration of 100, 50, 25, 12.5, 6.25 mg/L, respectively, the lethal rate of compound 67 on eggs of Tetranychus cinnabarinus was better than that of fluacrypyrim.
In the cases where compound 67 and fluacrypyrim were given at a concentration of 5, 2.5, 1.25, 0.625, 0.3125 mg/L, respectively, the lethal rate of compound 67 on nymphs of Tetranychus cinnabarinus was better than that of fluacrypyrim.
