An oxidative cross-coupling reaction between activated olefins and vinyl boronate derivatives has been developed for the highly stereoselective construction of synthetically useful (E,E)-1,3-dienes. The highlight of this reaction is that exclusive stereoselectivity (only E,E-isomer) was achieved from a base-free, ligand-free, and mild catalytic condition with a less expensive [RuCl2(p-cymene)]2 catalyst.

A resin-supported peptide catalyst (see box in the scheme) was used in the title reaction. The inherent regioselectivity was overcome by the peptide catalyst to promote the 1,6-selective reaction prior to 1,4-reduction. High stereoconvergence was also achieved when using a mixture of geometric isomers of the starting aldehydes. Ach=1-amino-1-cyclohexanecarboxylic acid. Copyright

By using of 3-methoxycarbonyl-2-methyl-2-propenylidenetriphenylarsorane (4) as isoprenoid reagent, 5-substituted 3-methyl-2,4-pentadienoic esters 6A and 6B (ABA ester analogs) were synthesized in 88-98percent yields under mild conditions.
