A short total synthesis of the cytotoxic natural product pachastrissamine is described. The synthesis includes eight steps starting from Garner's aldehyde and proceeds in 20% overall yield. Pd(0)-mediated intramolecular cyclisation and Ru-mediated cross-metathesis are the key reactions in this sequence. (c) 2007 Elsevier Ltd. All rights reserved.

A short route for the synthesis of Pachastrissamine (Jaspine B), an anhydrosphingosine derivative, and all three of its diastereomers is presented. The route consists of only 9 steps from the commercially available Garner's aldehyde. The furan framework is formed via an η3-allylpalladium intermediate.
