Separation of enantiomers by lipase-catalyzed fluorous-phase delabeling
摘要:
Simultaneous enantiomer-selective fluorous-phase delabeling and kinetic resolution was achieved by lipase-catalyzed alcoholysis of highly fluorinated esters of racemic alcohols. The separation of the fast-reacting delabeled enantiomers and the slow-reacting fluorous-phase labeled enantiomers was performed very efficiently by partition in an organic/fluorous biphasic solvent system.

[reaction: see text] Kinetic resolution of a fluorous ester rac-1 with Candida antarctica B lipase provided a mixture of enantioenriched alcohol (R)-2 and fluorous ester (S)-1. The mixture was subjected to a fluorous triphasic reaction to give both enantiomers of 1-(2-naphthyl)ethanol 2 in high ee without chromatographic separation or fluorous-organic liquid-liquid extractive purification.
