  Asymmetric Synthesis of Sulfinamides Using (−)-Quinine as Chiral Auxiliary

  摘要：

  A process has been designed and demonstrated for the asymmetric synthesis of sulfinamides using quinine as auxiliary. A variety of chiral sulfinamides including N-alkyl sulfinamides with diverse structure were prepared in good yields and excellent enantioselectivity starting from easily available and inexpensive reagents. The auxiliary quinine could be recovered and recycled.

  An efficient diastereoselective route for the preparation of chiral oxathiazine 2-oxide scaffolds as sulfinyl transfer agents, using tert-butanesulfinamide (tBSA) both as the source of chirality and as the precursor to the required nitrogen electron withdrawing group on the scaffold, was developed. This methodology allows the introduction of different substituents on the chiral scaffold, using commercially

  使用叔丁烷亚磺酰胺（tBSA) 作为手性来源和支架上所需的氮吸电子基团的前体被开发出来。该方法允许使用市售试剂和标准合成转化在手性支架上引入不同的取代基。合成的支架在对映体富集的亚磺酰胺的制备中进行了测试，提供了与文献中迄今为止提出的亚磺酰基转移剂相当的结果，并打开了进一步阐述这些支架的可能性，目的是在固相上支持它们以促进它们的回收和再利用。

  Simple and practical asymmetric synthesis of functionally differentiated aminoindanol based endo-N-sulfonyl 1,2,3-oxathiazolidine-2-oxide as sulfinyl transfer agents are developed. The importance of these new and unique sulfinyl transfer reagents are exemplified by the expedient production of several sulfinamide ligands, including either enantiomer of (R)-tert-butanesulfinamide in excellent yields and enantiopurities.
