Abstract
Racemic 2,3-diphenylbutane-1,4-diol (±)-1 is resolved to obtain the corresponding (R,R)-isomer in 98% e.e. through reaction with (S)-proline and boric acid. Partially resolved (R,R)-(-)-1 and (S,S)-(+)-1 have been enriched to obtain samples of 95 and 97% e.e. through reaction with (S)-proline and boric acid. Diastereomeric 1,4-diphenylbutane-1,4-diol 2 has been purified to obtain the (R,R)-isomer in 98% e.e. using (S)-proline and boric acid.
