  Chiral linker 5: scope and limitations of arylsubstituted m-hydrobenzoins as solid supported open chain chiral auxiliaries for diastereoselective syntheses

  摘要：

  The applicability of five aryl substituted m-hydrobenzoin ethers already tested in the L-Selectride (R) mediated stereoselective reduction of phenylglyoxylates as open chain chiral auxiliaries was further investigated via the alpha-alkylation of propionates, the addition of n-BuZnCl to phenylglyoxylates and the Diels-Alder reaction of acrylates with cyclopentadiene as model reactions. As up to 90% cle could be achieved in the solution phase, two optimized auxiliary structures were immobilized on commercially available Wang-resin and applied as a reusable solid supported chiral auxiliaries in the same type of reactions.

  Chiral linker. Part 3: Synthesis and evaluation of aryl substituted m-hydrobenzoins as solid supported open chain chiral auxiliaries for the diastereoselective reduction of α-keto esters

  摘要：

  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 (R) 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.
