Procedure

Starting from 4-iodophenyl methyl ketone, which is reduced to the racemic alcohol and converted to (±)-1-(4-iodophenyl)ethyl chloroacetate, the racemic ester is subjected to stereoselective enzyme hydrolysis. The remaining (S)-isomer of the ester is separated from the (R)-alcohol and transesterified to give (S)-1-(4-iodophenyl)ethanol (ee >98%) III.

Workup

  1. customThe remaining (S)-isomer of the ester is separated from the (R)-alcohol
