  Stereoselective total synthesis of Jaspine B (Pachastrissamine) utilizing iodocyclization and an investigation of its cytotoxic activity

  摘要：

  The stereoselective synthesis of Jaspine B has been achieved from easily available (S)-Garner's aldehyde. The trisubstituted tetrahydrofuran core of Jaspine B was constructed by utilizing a diastereoselective iodocyclization as the key step. Deiodination and debenzylation were performed in a single step by using n-Bu3SnH and ABCN as a conjugate catalyst system. The in vitro cytotoxicity of compounds 1 and la against 3 human cancer cell lines-A549 (lung), MCF7 (breast), and KB (oral): and a non-cancer cell line (NIH3T3) was determined by sulphorhodamine B based assay.

  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.

  The natural cytotoxic marine compound, jaspine B, is stereo selectively synthesized from D-Xylose in 11 linear steps with a 23.9% overall yield. The key step in the synthesis involves an iodine-induced debenzylation of a primary alcohol and the subsequent 2,5-cyclization to fit the required configuration of jaspine B. A preliminary bioassay shows strong inhibition activities against human MDA231, Hela, and CNE cell lines, indicating potential usage in various cancer treatments. (c) 2006 Elsevier Ltd.
