Lipase-mediated desymmetrization of glycerol with aromatic and aliphatic anhydrides
摘要:
Chirazyme L-2 (Candida antarctica) catalyzed esterification of glycerol with aromatic and aliphatic anhydrides in 1,4-dioxane is described. All the aromatic monoacylglycerols (MAGs) were produced as (R)-enantiomers, while aliphatic MAGs were obtained either as racemic mixtures or the (S)-enantiomers. The influence of substituted aromatic rings, chain length, and presence of a conjugated double bond in the acyl donor moiety on the enantiotopic selectivity as well as the efficiency of the enzyme was studied.
