Preparation method of 2,4-dichlorophenoxyacetic acid and salt thereof

The invention provides a preparation method of 2,4-dichlorophenoxyacetic acid and a salt thereof, wherein the preparation method includes the following steps: S1) carrying out a reaction of phenol andchloracetic ester under alkaline conditions to obtain phenoxyacetic ester; S2) carrying out selective chlorination reaction of the phenoxyacetic ester with a chlorinating agent under the action of acatalyst A and a catalyst B to obtain 2,4-dichlorophenoxyacetic ester, wherein the catalyst A is Lewis acid, and the catalyst B is C5-22 thioethers, thiazoles, isothiazoles and thiophenes or halogenated derivatives thereof; and S3) carrying out hydrolysis reaction of 2,4-dichlorophenoxyacetic ester under acidic conditions to obtain 2,4-dichlorophenoxyacetic acid; or after 2,4-dichlorophenoxyaceticester is obtained, carrying out an alkaline hydrolysis reaction with an alkaline compound to obtain 2,4-dichlorophenoxyacetate. The production and use of 2,4-dichlorophenol with unpleasant odor are avoided, the production of dioxins is eliminated, the yield of products is improved, and the output of three wastes is greatly reduced.

Preparation method of phenoxycarboxylic acid choline salt

The invention provides a preparation method of a phenoxycarboxylic acid choline salt, wherein the preparation method includes the steps: S1, carrying out condensation reaction of phenol or o-cresol with chlorocarboxylic ester in the presence of alkaline substances to obtain phenoxycarboxylic ester; S2, carrying out selective chlorination of the phenoxycarboxylic ester with a chlorinating agent inthe presence of a first catalyst and a second catalyst to obtain chlorobenzoxycarboxylic ester; and S3, after reaction of trimethylamine with ethylene oxide, adding the chlorophenoxycarboxylic acid ester, and carrying out alkaline hydrolysis reaction to obtain the phenoxycarboxylic acid choline salt. Compared with a conventional synthesis technology, the preparation method effectively avoids the production and use of chlorophenols with unpleasant odor, radically eliminates the production of highly toxic dioxins, and greatly improves the product quality and the operation environment of the production site; with phenol as the raw material, through condensation, selective chlorination and alkaline hydrolysis, the high-quality phenoxycarboxylic acid choline salt is obtained, the loss of effective ingredients is effectively avoided and the yield of the product is increased.

Aryloxyacetic esters structurally related to α-Asarone as potential antifungal agents

A series of aryloxyacetic ester analogues 8-13 was synthesized based on the potential pharmacophores of the antifungal agents α-Asarone (1) and 2-5. Their antifungal activity was tested in vitro for their growth inhibitory activities against pathogenic fungi. The in vitro antifungal evaluation of these alkyl and aryl esters shows that derivatives 10 displayed the highest antifungal and fungicidal activities against Cryptococcus neoformans and C. gattii. These results support the idea that the phenoxyacetic frame is a potent pharmacophore for the design of potential antifungal drugs. Graphical Abstract: [Figure not available: see fulltext.]
