Abstract


Chiral compounds is an important component of the macromolecular biological systems , hot and difficult problems of modern drug synthesis focus , the use of biological lipase chiral separation technology is an important method to get a single configuration of chiral molecules , in view of the lipase higher costs , and recovery difficult , so it is very necessary to establish lipase recovery technology . In the full analysis of the domestic and foreign lipase fixed recovery technology based on the proposed use of the \successfully achieved lipase effectively fixed , and its application chiral pesticides mefenoxam racemic intermediate 2 - (2,6 - dimethyl- phenylamino ) propionate split , the success sieving useful R-configuration of the 2 - (2,6 - dimethyl- phenylamino) -propionic acid; for both racemic the stability of the 2 - (2,6 - dimethyl- phenylamino ) propionic acid poor, the need for real - time quantitative requirements , to establish the standard curve in the analysis by liquid chromatography under the conditions of the racemic . Papers recycling the repeated use of the lipase , and to obtain a more satisfactory result .
