  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.
