  Asymmetric synthesis of α,α-disubstituted α-amino alcohol derivatives

  摘要：

  We herein report an asymmetric synthesis of alpha,alpha-disubstituted alpha-amino alcohol derivatives 3, key intermediates of a novel immunomodulator, using enzymatic desymmetrization of 2-alkyl-2-tert-butoxycarbonylamino-1,3-propanediols 1a and 1b. This method makes it possible to prepare a chiral analogue of FTY720 4. These synthetic procedures allow for a broad structure variation in order to evaluate structure-activity relationships and the mechanism of action for sphingosine 1-phosphate-1 (SIP1) receptor agonist.
