| titleOfInvention | Optically active secondary alkyne alcohol by biochemical technique |
| abstract | PURPOSE: To readily and efficiently obtain the subject compound useful as medicines, agricultural chemicals, etc., in high purity by subjecting an ester of a racemic alkyne alcohol to asymmetric hydrolytic reaction in the presence of a specific enzyme under specified pH conditions. n CONSTITUTION: An (R,S)-ester expressed by formula I (l and n are 0-4; m is 0 or 1; C* is asymmetric carbon atom) [e.g. (R,S)-3-acetoxy-1-butyne] is subjected to hydrolytic reaction in the presence of an enzyme (preferably a lipase, etc.) having the ability to react with the compound expressed by formula I and preferentially carry out asymmetric hydrolytic reaction with either of the R- and S-isomers at pH≥3 and resolved into an optically active alcohol, expressed by formula II and rich in either of the R- and S-isomers. n COPYRIGHT: (C)1991,JPO&Japio |
