| titleOfInvention | Enzyme racemic resolution method for pantolactone |
| abstract | (57) [Summary] (Modified) [Object] To provide a method for producing (R)-(-)-pantolactone having high optical purity. ## STR1 ## Formula I (Formula R 1 is a C 1 -C 18 haloalkyl group, (wherein halogen is chlorine, bromine, iodine or fluorine) or a phenyl group, and the phenyl group is chlorine, bromine, iodine, fluorine, cyanide, nitro, carboxyl or Optionally substituted by an alkoxy group having 1 to 4 carbon atoms, R 2 is hydrogen or a methyl group) and a vinyl ester represented by the formula II is prepared in the presence of lipase from Pseudomonas or porcine pancreas. The method for enzymatic resolution of racemic pantolactone by reacting with racemic pantolactone represented by and then separating the remaining optically active (R)-(−)-pantolactone from the formed pantractol ester. |
