Paragraph 0114-0119, (2017/08/29)
The invention provides a heterocycle-containing glyphosate derivative. The heterocycle-containing glyphosate derivative has a structure which is shown as the formula (I); in the formula, M1 is selected from H, NH4, K or Na; M2 is selected from H, NH4, K or Na; n is 0 to 5; R is selected from the substances which are shown as the formula in the specification, wherein R' is selected from an alkyl of H or C1 to C4. The heterocycle-containing glyphosate derivative provided by the invention is used as an herbicide, is prevented from being compounded with other pesticides to produce chemical reactions, and is simple in using method and good in pesticide effect. A synthesis method provided by the invention is simple, green and environmentally-friendly, and has good atom economy.

A herbicide containing an optical isomer of R-form of a diphenyl ether derivative represented by formula (I), which has a more excellent herbicidal activity with a smaller dose thereof than one containing the corresponding racemate. The use of the compound of formula (I) together with various herbicides known per seserves to improve the fast-acting property and widen the herbicidal spectrum with a small dose.

Three-component condensation of glycine ethyl ester hydrochloride, formalin and hydrophosphorous compounds 1-3 was carried out to the esters 4-6, which after acid hydrolysis led to the free N-phosphino-, phosphonomethylated glycines 7-9.Strict selectivity in enzyme-catalyzed hydrolysis of phosphino-, phosphono acid esters was established.The enzyme phosphodiesterase I catalyzed the hydrolysis of the ester 4, 5 and 6 to the corresponding 10, 11 and 12.Lyophilyzed bee venom hydrolyzed the ethoxycarbonyl groups of 4-6 to the corresponding free glycines 7-9, and the enzyme alkaline phosphatase contributed to the hydrolysis only of the one from the two diethoxyphosphono groups of the substrate 6 to the monophosphono ester-13.Proteolytic enzymes α-chymotrypsin, protease and alkaline mesintericopeptidase catalyzed only hydrolysis of the ethoxycarbonyl groups of the substrates 5 and 6 to the free carboxylic acids 14 and 15 which after treatment with phosphodiesterase I or bee venom liberated glycines 8 and 9, respectively.It was established that the enzymes α-chymotrypsin and alkaline mesintericopeptidase were completely inhibited by H-P(O)-group containing substrates 4 and 10, while α-chymotrypsin was partially inhibited from substrates 11, 12 and 13 containing -P(O)OH-group.
