  Stereoselective Conjugate Radical Additions:  Application of a Fluorous Oxazolidinone Chiral Auxiliary for Efficient Tin Removal

  摘要：

  A series of asymmetric free-radical-mediated intermolecular conjugate additions using a fluorous oxazolidinone chiral auxiliary has been completed. The fluorous auxiliary facilitated product isolation using fluorous solid phase extractions (FSPE), effectively removing excess organic and organometallic reagents. Parallel reactions carried out with a similar but nonfluorous norephedrine-derived oxazoldinone demonstrated the superior stereoselectivity and purification obtainable with the fluorous chiral auxiliary.

  Practical Synthesis of Fluorous Oxazolidinone Chiral Auxiliaries from α-Amino Acids

  摘要：

  A series of new fluorous-supported oxazolidinone chiral auxiliaries has been prepared using a versatile and general five-step pathway, starting from readily available chiral a-amino acids. The key feature of this synthesis is the efficient generation of a suitably active perfluoroalkyllithium species. By use of this protocol, the auxiliaries can be obtained in high enantiomeric purity and on multigram scales from L-phenylalanine and L-valine with overall yields as high as 55%. The new methodology also incorporates fluorous solid-phase extraction on the large scale, allowing bulk quantities (up to 25 g) of fluorous compounds to be purified from the crude reaction mixture.
