| titleOfInvention | A kind of synthetic method of (S)-metolachlor |
| abstract | The invention discloses the synthetic method of one (S)-metolachlor, for raw material with Pfansteihl ester, first carry out the halo of alcohol, chiral carbon generation configuration conversion, then the reduction of ester, the etherificate of alcohol is carried out, carry out nucleophilic substitution reaction with 2-methyl-6-ethylaniline again and generate secondary amine, last and chloroacetyl chloride reacts and generates target product (S)-metolachlor.Compared with existing synthetic route, the present invention has the advantages that starting raw material is cheap and easy to get, Atom economy good, cost is low, stereoselectivity is good and reaction conditions is gentle. |
