  A common strategy for the stereoselective synthesis of anhydrophytosphingosine pachastrissamine (jaspine B) and N,O,O,O-tetra-acetyl d-lyxo-phytosphingosine

  摘要：

  The highly stereoselective Grignard addition on chiralimine 8 and opening of chiral epoxide 9 with Grignard reagent have been used as key steps in the stereoselective synthesis of cytotoxic anhydrophytosphingosine pachastrissamine (jaspine B) and N,O,O,O-tetra-acetyl D-lyxo-phytosphingosine.

• Stereocontrolled synthesis of cytotoxic anhydrosphingosine pachastrissamine by using [3.3] sigmatropic rearrangement of allyl cyanate

  A new route for the synthesis of the cytotoxic anhydrosphingosine pachastrissamine has been developed. [3.3] Sigmatropic rearrangement of an allyl cyanate was employed to construct the allyl amine moiety in 2 from the chiral C-4 unit 3. Oxidative cleavage of the double bond in 2, followed by THF ring formation furnished the target pachastrissamine.

• Double stereodifferentiation in asymmetric dihydroxylation: application to the first diastereoselective synthesis of l-xylo-[2R,3S,4S]-C18-phytosphingosine

  日期：2000.12

  The first diastereoselective synthesis of L-xylo-(2R,3S 4S)-C-18-phytosphingosine (1) has been achieved by double stereodifferentiation of enantiomerically enriched terminal olefin 14 using (DHQD(2))-PHAL ligand in an asymmetric dihydroxylation with a diastereomeric ratio of 83:17. This phytosphingosine was fully characterized by the physical and spectral data of the corresponding tetraacetate 21. (C) 2000 Elsevier Science Ltd. All rights reserved.
