Enzymatic Resolution and Separation of Secondary Alcohols Based on Fatty Esters as Acylating Agents
Monteiro, Carlos M.; Afonso, Carlos A. M.; Lourenco, Nuno M. T.
Journal of Chemical Education, v87 n4 p423-425 Apr 2010
The enzymatic resolution of "rac"-1-phenylethanol using ethyl myristate as acylating agent and solvent and "Candida antarctica" lipase B (CAL-B) as biocatalyst was demonstrated with catalyst and medium reuse. Both enantiomers of 1-phenylethanol were isolated by sequential enzymatic reactions and product distillations. From the first enzymatic reaction, ("S")-1-phenylethanol was isolated with a 41% yield and 80% enantiomeric excess, and from the second enzymatic reaction, ("R")-1-phenylethanol was isolated with a 56% yield and 63% enantiomeric excess. (Contains 2 figures and 1 note.)
