Enantiopure N‐Benzyloxycarbonyl‐β 2 ‐amino Acid Allyl Esters from Racemic β‐Lactams by Dynamic Kinetic Resolution using Candida antarctica Lipase B

Abstract The dynamic kinetic resolution of α‐substituted racemic β‐lactams by alcoholytic ring‐opening, catalyzed by immobilized lipase B from Candida antarctica is described. With this process, a variety of racemic α‐substituted N ‐Cbz‐azetidinones (Cbz=benzyloxycarbonyl) was transformed to the cor...

Description
Summary:Abstract The dynamic kinetic resolution of α‐substituted racemic β‐lactams by alcoholytic ring‐opening, catalyzed by immobilized lipase B from Candida antarctica is described. With this process, a variety of racemic α‐substituted N ‐Cbz‐azetidinones (Cbz=benzyloxycarbonyl) was transformed to the corresponding N ‐Cbz‐protected β 2 ‐amino acid allyl esters with high enantioselectivity (up to 99%) and high yields (up to quantitative) at room temperature. magnified image
