The construction of a library of natural and related polyacetylenes using a convergent synthetic strategy based on a palladium mediated cross-coupling reaction is described. The systematic synthetic study led to all possible alkene isomers of the hydroxy matricaria esters 29-32, and the corresponding tiglates 1-4. The synthesis of many of these compounds is described for the first time. (C) 2009 Elsevier Ltd. All rights reserved.

The naturally occurring polyacetylene Bupleurynol was synthesized in a convergent and stereospecific manner using a series of metal-mediated cross-coupling reactions. The synthesis demonstrates the utility of using a di-functional olefin template for the stereospecific synthesis of a disubstituted alkene product and its elaboration to a natural product target.
