  D-xylose derived oxazolidin-2-ones as chiral auxiliaries in stereoselective alkylations

  摘要：

  Chiral N-acylated oxazolidin-2-ones readily available from D-xylose have been demonstrated to undergo highly diastereoselective alkylation reactions via their lithium imide enolates to afford alpha-branched products. These are easily purified and hydrolyzed without difficulty allowing isolation of the desired ramified carboxylic acids in high enantiomeric excesses and to return the auxiliaries for reuse.
