The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: (R)-Ethyl 4-chloro-3-hydroxybutanoate(SMILESS: O=C(OCC)C[C@@H](O)CCl,cas:90866-33-4) is researched.Synthetic Route of C18H13BCl3F4N3O. The article 《Discovery of a reductase-producing strain recombinant E. coli CCZU-A13 using colorimetric screening and its whole cell-catalyzed biosynthesis of ethyl (R)-4-chloro-3-hydroxybutanoate》 in relation to this compound, is published in Bioresource Technology. Let’s take a look at the latest research on this compound (cas:90866-33-4).
An NADH-dependent reductase (SsCR) was discovered by genome data mining. After SsCR was overexpressed in E. coli BL21, recombinant E. coli CCZU-A13 with high reductase activity and excellent stereoselectivity for the reduction of Et 4-chloro-3-oxobutanoate (COBE) into Et (R)-4-chloro-3-hydroxybutanoate ((R)-CHBE) was screened using one high-throughput colorimetric screening strategy. After the reaction optimization, a highly stereoselective bioreduction of COBE into (R)-CHBE (>99% ee) with the resting cells of E. coli CCZU-A13 was successfully demonstrated in Bu acetate-water (10:90, volume/volume) biphasic system. Biotransformation of 600 mM COBE for 8 h in the biphasic system, (R)-CHBE (>99% ee) could be obtained in the high yield of 100%. Moreover, the broad substrate specificity in the reduction of aliphatic and aromatic carbonyl compounds was also found. Significantly, E. coli CCZU-A13 shows high potential in the industrial production of (R)-CHBE (>99% ee) and its derivatives
