Development of an improved immobilized CAL-B for the enzymatic resolution of a key intermediate to odanacatib

An immobilized form of Candida antarctica lipase B (CAL-B) has been developed with enhanced stability and activity compared to commercially available preparations. The immobilized CAL-B is more active, and 15 times more stable than the previously used preparation. This permits a continuous dynamic kinetic resolution process that is significantly less expensive than the original batch process, and with a 3-fold reduction in the process E-factor.

An efficient chemoenzymatic approach to (S)-γ-fluoroleucine ethyl ester

(Chemical Equation Presented) An asymmetric synthesis of (S)-γ-fluoroleucine ethyl ester 1 is described. The key transformation involves a lipase-catalyzed dynamic ring-opening of 2-(3-butenyl)azlactone 7b with EtOH to give amide ester (S)-6b in 84% enant
