A convenient synthesis of the phytotoxic natural product epipyriculol has been accomplished in 17 steps from methyl L-tartrate. The synthetic strategy is based upon the use of a butanediacetal-protected scaffold as central core from which the alkenyl side chains were assembled. (C) 2008 Elsevier Ltd. All rights reserved.

A new method for the synthesis of dienes and enynes containing chiral 1,2-diols is described. The strategy is based on the Pd-catalysed cross-coupling reactions of a series of vinyl and alkynyl asymmetric butanediacetal-protected building blocks. After the coupling, removal of the protectinggroup leads to the desired functionalised dienes and enynes.
