A 3 - (methyl alkoxythiophene phosphoryl) propionic ester preparation method of compound
-
Paragraph 0019; 0020, (2017/02/28)
The invention discloses a method for preparing 3-(methyl alkoxy phosphoryl group) propionate compound. Methyl phosphorous acid dialkyl and acrylate are taken as the raw material, and the reaction is carried out in a nonaqueous secondary solvent so as to obtain the 3-(methyl alkoxy phosphoryl group) propionate. According to the method, the Methyl phosphorous acid dialkyl and acrylate are taken as the raw material, the reaction solvent is the nonaqueous secondary solvent such as alcohol, carboxylic acid, and the like, besides being used as the solvent, the nonaqueous secondary solvent also can be reacted with alkyl anions generated in the reaction process so as to generate corresponding ether or carboxylic ester, the two alkoxy in the 3-(methyl alkoxy phosphoryl group) propionate are from methyl phosphorous acid and dialkyl and acrylate respectively, therefore, the method can be used for synthetizing the 3-(methyl alkoxy phosphoryl group) propionate with different alkoxy according to requirements, the reaction does not need to be carried out under anhydrous and anaerobic condition, the content of the product prepared by the method is more than 98%, and the yield of the product is over 95%.

Enantioselective Synthesis of Both Enantiomers of Phosphinothricin via Asymmetric Hydrogenation of α-Acylamido Acrylates
Zeiss, Hans-Joachim
, p. 1783 - 1788 (2007/10/02)
Both enantiomers of phoshinothricin (1), a naturally occuring amino acid that contains the unique methylphosphinate moiety, were prepared by asymmetric hydrogenation of α-acylamido acrylate precursors 7.L-1 and peptides containing L-1 are inhibitors of the enzyme glutamine synthetase (GS).Inhibition of GS is responsible for the antibiotical and herbicidal properties of these compounds.Synthesis of substrates 7 and parameters influencing the enantioselectivity are discussed.Substrate concentration and solvent polarity appear to have the most marked effects on enantiomeric excesses for a given catalyst system.Enantiomeric excesses reach 91percent for hydrogenations with (R,R)-NORPHOS- and (S,S)-CHIRAPHOS-derived catalysts.
