Five partly novel aryl substituted m-hydrobenzoins were synthesized and the corresponding desymmetrized hydrobenzoin ethers evaluated as open chain chiral auxiliaries in the L-Selectride mediated stereoselective reduction of phenylglyoxylates, resulting in de values of up to 91%. Two optimized auxiliary structures were immobilized on commercially available Wang-resin and applied as a reusable solid supported chiral auxiliary in the same type of reaction.

Analogs of ephedrine are obtained in 80percent yield in 3 steps from chiral arenechromium tricarbonyl complexes.Hence optically pure complexes afford optically pure analogs of ephedrine.
