The invention provides a method of using immobilized
Escherichia coli engineered bacterial cells to catalytically synthesize
statin drug chiral intermediates, tert-butyl (3R,5S)-6-chloro-3,5-dihydroxyhexanoate and (3R,5R)-tert-butyl-6-cyano-3,5-dihydroxyhexanoate. The method comprises: culturing
carbonyl reductase-containing
Escherichia coli engineered
bacteria, preparing immobilized cells, and synthesizing the novel
drug chiral intermediates, tert-butyl (3R,5S)-6-chloro-3,5-dihydroxyhexanoate and (3R,5R)-tert-butyl-6-cyano-3,5-dihydroxyhexanoate by
catalysis of the immobilized cells. The immobilized biological
Escherichia coli engineered bacterial cells are used in the method as the catalyst, the stability is good, the service life is long, tolerance to organic solvents is good, the catalyst is reusable, adding expensive external coenzymes is not required, the catalyst is capable of catalyzing the synthesis of
statin drug intermediates in an organic
phase reaction system, the productsare high in yield and purity, the production cost can be greatly reduced, the process steps can be simplified, emission of three wastes is reduced, and the method is very worthy of application in theindustrial production of
statin drug chiral intermediates.
