Definitions
- R 1 represents a hydrogen atom or an alkyl group having 1 to 6 carbon atoms, which may have a substituent, or R 2 represents a substituent.
- the present invention also provides an ester of [R, S) alkyne alcohol [ ⁇ ] in water or a mixed solvent of water and an organic solvent in the presence of the lipase and polyphenols. Reacts with water to form one optically active alkyne alcohol [II] by the hydrolysis reaction, while leaving the ester [ ⁇ ] of the other optically active alkyne alcohol (R, S) Provided is an optical resolution method for ester [ ⁇ ].
- the second method is represented by the following reaction formula.
- Examples of carriers for immobilizing lipase include polymers such as polystyrene, polypropylen, starch, and gluten, activated carbon, porous glass, cerite, zeolite, and the like. Inorganic materials such as iron ore, bentonite, alumina, silica gel, hydroxyapatite, calcium phosphate and metal oxides are exemplified. Carry and fix by the physical adsorption method. The immobilized lipase retains sufficient activity and stereoselectivity of the reaction after completion of the reaction and after recovery from the reaction solution, so that it can be reused repeatedly.
- Lipase AK Three Lipase AK, lipase P, lipase CES, and rhino from Schdomonas sepacia.
- Examples include Lase PS, lipase (both from Amano Pharmaceutical Co., Ltd.), and lipase MY (Meito Sangyo Co., Ltd.) derived from Candida silyline lace.
- reaction rate had reached 55.3%.
- an S-isomer ester remained in the reaction solution, and its optical purity was 80.0% e e.
- an R-form alcohol was formed in the reaction solution, and its optical purity was 64.0% e e.
- optically active alkyne alcohols and esters thereof obtained by the method of the present invention are important as synthetic raw materials or synthetic intermediates of optically active compounds such as drugs, aba drugs, and physiologically active substances.

Abstract
Procédé qui permet de synthétiser de grandes quantités d'alcynylalcools ayant une pureté optique élevée par des étapes simples avec un catalyseur relativement bon marché. On fait réagir un ester d'alcynylalcool (R, S) (I) avec un alcool en présence d'une lipase capable d'alcooliser stéréosélectivement l'ester sous forme R ou S dans un solvant organique à base d'éther. Il se forme ainsi un alcynylalcool optiquement actif (II), tandis que l'autre ester d'alcynylalcool optiquement actif (III) reste. Dans les formules, R1 représente H ou alkyle C¿1?-C6, et R?3¿ représente alkyle C¿6?-C12.
