title: Stereoselective synthesis of cytotoxic anhydrophytosphingosine pachastrissamine (jaspine B) from D-xylose.
abstract: The first naturally occurring anhydrophytosphingosine, pachastrissamine (jaspine B), a marine compound cytotoxic toward P388, A549, HT29, and MEL28 cell lines at IC(50) = 0.01 microg/mL level, has been stereoselectively synthesized from D-xylose in 10 linear steps with 25.7% overall yield.
