摘要:A method for chemical-biological cascade synthesis of L-phosphinothricin is carried out as follows: 3-(methylethoxyphosphinyl) ethyl propionate is synthesized by addition reaction from diethoxymethylphosphine and acrylic acid, then a condensation reaction is carried out with 3-(methylethoxyphosphinyl) ethyl propionate and sodium ethoxide as reactants, then the product is subjected to a hydrolysis reaction with diethyl oxalate to synthesize 4-(hydroxymethylphosphinyl)-2-oxobutyric acid, and finally, L-phosphinothricin is catalytically synthesized by taking 4-(hydroxymethylphosphinyl)-2-oxobutyric acid as a raw material, and using highly active and stable wet cells co-expressing phsophinothricin dehydrogenase and alcohol dehydrogenase or co-expressing a phsophinothricin dehydrogenase mutant and alcohol dehydrogenase as a biocatalyst, thereby solving the problems of existing L-phosphinothricin synthesis being tedious, low asymmetric amination reduction activity and poor stability.

摘要:SummaryThe present invention relates to a method for production of a compound according to formula (I):wherein R is alkyl, aryl, alkaryl, aralkyl,and wherein X is selected from the following structures (I-A), (I-B):wherein R¹, R² are independently selected from the group consisting of alkyl, aryl, alkaryl, aralkyl.The compounds according to formula (I) are important precursors in the synthesis of glufosinate, in particular L-glufosinate. In the method according to the present invention, easily accessible starting materials are employed. Thus, the method overcomes the disadvantages of prior art syntheses of L-glufosinate and its intermediates.
