Abstract

Diastereomerically pure (+)- and (−)-2,2-dimethyl-1,3-diphenyl-1,3-propanediols were synthesized starting from diethyl malonate and resolved through diesters of (−)-camphanic acid and also N-carbethoxy-l-proline. The absolute configuration of the (−)-enantiomer was established by X-ray crystallography.
