  DIASTEREOSELECTIVE ALKYLATION AND ALDOL REACTIONS MEDIATED BY THE d-MANNITOL-DERIVED OXAZOLIDIN-2-ONE AS A CHIRAL AUXILIARY

  摘要：

  Chiral N-acylated oxazolidin-2-ones readily available from D-mannitol have been demonstrated to undergo highly diastereoselective alkylation reactions via their lithium imide Z-enolates to afford a-branched products. Evans syn and non-Evans syn aldol products were also selectively obtained using this new auxiliary in high diastereomeric purity by simply changing the stoichiometry of TiCl4 and the nature of the amine base.
