Abstract
The enantiomers of the inhalation anesthetic agent, isoflurane (1-chlo ro-2,2,2-trifluoroethyl difluoromethyl ether), are prepared by a synth esis starting from 2,2,2-trifluoroethanol. (R)-(+)-Dehydroabietylamine is used as the resolving agent for the racemic acid intermediate 1. T he optical purities of both (S)-(+)- and (R)-(-)-isofluranes are deter mined to be >99% ee (enantiomeric excess) by chiral capillary gas chro matography.
