| titleOfInvention | A method of synthesis 2- amide groups -4- (O- alkyl methylphosphine acyl group) -2- butenoic acid and its ester |
| abstract | The invention belongs to a kind of pesticide intermediates for synthesizing herbicide technology field; more particularly to a kind of synthetic method of pesticide intermediate 2- amide groups -4- (O- alkyl methylphosphine acyl group) -2- butenoic acid and its ester; its elder generation is reacted with compound VI by Arbuzov with compound VII generates compound V; using sour hydrolysis compound IV; then compound IV and compound III; reaction obtains compound II under condensation reagent and catalyst action, and final compound II hydrolyzes to obtain compound I.Compared to existing synthetic route, route steps of the present invention are short, atom economy, and stereoselectivity is high and process environments are friendly, and cost is relatively low, there is industrial prospect. Wherein R 1 For C 1‑4 Alkyl；R 2 , R 3 For-C n H 2n+1 , n=1,2,3,4 or R 2 And R 3 For-C m H 2m , m=2,3；R 4 For C 1‑4 Alkyl, C 6‑10 Aryl；R 5 For hydrogen, C 1‑4 Alkyl；X is chlorine, bromine. |
