  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.

  The present invention relates generally to perfluoroalkyl chiral auxiliary compounds and methods of manufacture. These compounds have the functionality to effectively support the synthesis of chiral compounds in single reactions, high-throughput parallel reactions, or combinatorial reactions The invention relates to two oxazolidinone chiral auxiliaries (1) and (2): wherein R f is a perfluoroalkyl group having the general formula (CH 2 ) x —C y F 2y+1 where x=1-5 and y=4-10 and wherein B is an unfunctionalized aryl, alkyl or arylalkyl group in a preferred embodiment, x=2 and y=6 and B is derived from unfunctionalized amino acids The amino acids may be from either the D- or L-series, and are preferably enantiomerically pure or in very high enantiomeric excess in either configuration.

  本发明涉及全氟烷基手性辅助化合物及其制造方法。这些化合物具有有效支持手性化合物在单反应、高通量并行反应或组合反应中合成的功能。本发明涉及两种噁唑烷手性辅助剂（1）和（2）：其中Rf是具有一般式（CH2）x - CyF2y + 1的全氟烷基，其中x = 1-5，y = 4-10，B是非功能化芳基，烷基或芳基烷基组，在优选实施例中，x = 2，y = 6，B来源于非功能化氨基酸。氨基酸可以来自D-或L系列，并且最好在任何构型中具有对映纯或非常高的对映选择性。

  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.
