Technical Field
The invention relates to the technical field of organic compound preparation, in particular to a preparation method of chlorantraniliprole insecticide.
Background
The 1-pyridyl pyrazole amide compound has broad spectrum activity and is an important component of bisamide insecticides (such as chlorantraniliprole, cyantraniliprole, tetrachloro-cyantraniliprole, cyclopropane carboxamide and the like). The bisamide insecticide is an insecticide product which is most concerned by the market after the neonicotinoid insecticide, and is also the insecticide product which is the fastest growing in recent years. The outstanding bisamide insecticide represents chlorantraniliprole, not only is one of four milestones (phenothrin, imidacloprid, abamectin and chlorantraniliprole) in the field of insecticide research and development, but also is a leaderboard champion for insecticide sale since 2014, wherein the annual sale amount of the chlorantraniliprole 2014 reaches 14.7 billion dollars, and the annual sale amount of the chlorantraniliprole 2019 reaches 17.5 billion dollars. Cyantraniliprole, test code: DPX-HGW86, also known as Cyazypyr. The o-formamido benzamide pesticide which is discovered and developed by DuPont in 2007 and first marketed in Argentina in 2012. Cyantraniliprole is a sister product of chlorantraniliprole, and has wider application range and wider insecticidal range compared with the chlorantraniliprole. The sales of cyantraniliprole is continuously increasing, and the sales of cyantraniliprole reaches $ 1.20 billion in 2019. Tetrachloro worm amide, test code: SYP-9080, discovered and developed by Shenyang chemical research institute in 2008, temporarily registered in China in 2013, and formally registered anthranilamide insecticides in China in 2017. The tetrachlorantraniliprole is the most economic bisamide insecticide and can be used for crops such as cabbage, rice, corn and the like to prevent and control pests with chewing mouthparts such as cnaphalocrocis medinalis, corn borers and the like. The sales of the tetrachlorantraniliprole are continuously increased and reach $ 0.30 hundred million in 2019. Cyprodinil, test code: IKI-3106, a anthranilamide insecticide which was first marketed in Korea in 2017, was discovered and developed by Shiyuan corporation in 2005. The sales of cyprodinil continue to increase, reaching $ 0.22 million in 2019.
The synthesis methods of chlorantraniliprole insecticides are reported more, for example, the synthesis method of chlorantraniliprole is as follows: wangyanjun et al [ pesticide 2010, 49(3): 170-5-propanoic acid 173] use 3-bromo-1- (3-chloropyridine-2-pyridyl) -1H-pyrazole-5-carboxylic acid as raw material, add 5-chloro-3-methyl-2-aminobenzoic acid and acetonitrile, then cool down and drop 3-methylpyridine and acetonitrile solution of methylsulfonyl chloride in turn, add right amount of water after reaction, filter by suction to obtain yellow solid 6-chloro-2- (3-bromo-1- (3-chloropyridine-2-pyridyl) -1H-pyrazol-5-yl) -8-methyl-4H-3, 1-benzoxazine-4-one. The compound is dissolved in acetonitrile, and 25% methylamine water solution is dripped to obtain white solid chlorantraniliprole with the total yield of 76.1%. The method is a common synthesis method of chlorantraniliprole, but has the disadvantages of low total yield, complex operation, large amount of three wastes and high production cost. For example, the synthesis method of the tetrachloro insect amide: plum bin and the like (modern pesticides 2014 (3): 17-20) take acetonitrile as a solvent, and 1- (3, 5-dichloropyridin-2-yl) -3-bromo-1H-pyrazole-5-carboxylic acid and 3, 5-dichloro-2-aminobenzoic acid are reacted under the action of methylsulfonyl chloride and triethylamine to obtain 2- [ 3-bromo-1- (3, 5-dichloropyridin-2-yl) -1H-5-pyrazolyl ] -6, 8-dichloro-4H-benzo [ d ] [1,3] oxazin-4-one; the compound was then reacted with 30% aqueous methylamine in tetrahydrofuran to give the tetrachloro-worm-amide in 19.4% overall yield. The method has the advantages of low total yield, complex operation, large amount of three wastes and high production cost.
