(S)-N-Boc-3-hydroxypiperidine ((S)-NBHP) is an important chiral intermediate for the synthesis of ibrutinib, an anticancer drug targeting B-cell malignancies. An NADPH-dependent reductase (YDR541C) from Saccharomyces cerevisiae was isolated and found to show excellent catalytic activity in the production of (S)-NBHP. The reductase YDR541C was cloned and overexpressed in Escherichia coli BL21 (DE3), purified to homogeneity, and its catalytic properties were studied. Furthermore, an ethyl caprylate-water (1:1, v/v) biphasic system was introduced to alleviate product inhibition. After optimization of the reaction, as much as 1200 mM N-Boc-piperidin-3-one (NBPO) (240 g/L) was asymmetrically reduced to (S)-NBHP within 6 h, resulting in a yield of 99%, an enantioselectivity of >99.5% ee, and a total turnover number (TTN) of 8000. These results indicate great potential for industrial application.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Electric Literature of 143900-43-0, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 143900-43-0, in my other articles.
