PROCESS FOR PREPARING R-2-ACYLOXY-1-ARYLPROPANONE AND S-2-HYDROXY-1-ARYLPROPANONE DERIVATIVE FROM 2-HYDROXY-1-ARYLPROPANONE BY USING LIPASE

摘要

Provided is a process for preparing R-2-acyloxy-1-arylpropane derivative and S-2-hydroxy-1-arylpropanone derivative having a high optical purity from a racemic 2-hydroxy-1-arylpropanone derivative with a high yield in an industrial scale. The process for preparing an S-2-hydroxy-1-arylpropanone derivative represented by a formula 2 and an R-2-acyloxy-1-arylpropane derivative represented by a formula 3 comprises a step of acylating a racemic 2-hydroxy-1-arylpropanone represented by a formula 1 in the presence of a lipase catalyst derived from candida antartica by using an acyl donating agent. In formulae 1-3, X is H or Cln, Brn, Fn, acyl, alkyl, nitro or a combination thereof (n is 1 or 2); and R is a C1-C10 saturated or unsaturated alkyl group.
