-
Paragraph 0182-0184, (2019/10/17)
The invention belongs to the technical field of insecticides and acaricides, and particularly relates to quinoline derivatives, and a preparation method and a use thereof, and concretely provides compounds represented by formula (I), and stereoisomers, racemates, tautomers, isotope labels, oxynitrides, pharmaceutically acceptable salts or solvates thereof. The compounds of the formula (I) have an excellent activity against various pests and pest mites in the agricultural field or other fields. The compounds can achieve an excellent control effect at a very low dosage, so the compounds can be used to prepare insecticides and/or acaricides. In addition, the preparation steps of the compounds of the invention are simple, and the product yield is high, so that the compounds have a good application prospect.
An efficient synthesis of O,O- di propyl (E)-2-[1-methyl 2-oxopropylidene]phosphorohydrazidothiolate (E) oxime and its analogues: A potential marine toxin

An efficient method for the synthesis of Ptychodiscus brevis toxin O,O- di n-propyl (E)-2-[1-methyl 2-oxopropylidene]phosphorohydrazidothiolate (E) oxime (TG-1) and its analogues has been developed using thermally stable and recyclable silica gel and Na2SO4 as a condensing agent and water scavenger, respectively. The compounds were evaluated against fish Rasbora daniconius by determining the LC50 and LC90 values. The results of biological evaluation showed that these compounds have high degree of toxicity.

The reaction of the title phosphono- and phosphoro-thiolates with sulphuryl chloride and halogens involves in every case the formation of intermediates containing two phosphorus atoms >P+(SR)OP(O)- (X = SO2Cl or halogen).The formation of the latter in the course of chlorinolysis of phosphorus thiolesters is suggested to be responsible for the occurrence of a mechanism involving retention of configuration.The effect of the structure of the reactants and the nature of solvent on the reaction stereochemistry is discussed.
