| titleOfInvention | Production of optically active compound having pyridine skeleton |
| abstract | PURPOSE:To efficiently resolve the racemic mixture of a specific compound into an optically active ester and an enantiomer thereof, by biochemically subjecting the racemic mixture to an asymmetrical ester interchange reaction. CONSTITUTION:(R and S) compounds of formula I {X is a group of formula II-IV [Z<1>-Z<4> are hydrogen, halogen, cyano, amino, a group of formula V (W<1>-W<5> are hydrogen, halogen, cyano, etc.), 1-20C alkyl or alkoxy]; Y is halogen, hydrogen, cyano or trifluoromethyl; R and Q are 1-20C alkylene; m and n are 0 or 1} are subjected to an ester interchange reaction with an ester (e.g.: triglyceride) preferentially reacting with either of the (R and S) compounds of formula I in the presence of an enzyme (e.g.: lipase) having an ability of the asymmetrical ester interchange reaction substantially in the absence of water. Thereby, the compounds are resolved into the optically active compound rich in either of the R- and S-isomers and an ester thereof. |
