Kinetic resolution of propargylic alcohols via stereoselective acylation catalyzed by lipase PS-30

By using lipase PS-30 as catalyst, the kinetic resolution of a series of racemic propargylic alcohols has been achieved via stereoselective acylation. The value of kinetic enantiomeric ratio (E) reached up to 139. Substituent effect is briefly discussed.

Fourteen examples. Values of the kinetic enantiomeric ratio (E) up to 139.Figure optionsDownload as PowerPoint slide
