Stereoselective Mizoroki-Heck arylation of (E)-7-methylocta-2,6-dienoic acid with aryl iodide catalyzed by Pd(OAc)2 and P(o-MeC6H4)3 was optimized, and the yields were improved under the condition of excess Et3N both as the base and solvent with reduced amount of catalysts. Twenty (E)-3-aryl-7-methylocta-2,6-dienoic acids were directly synthesized via Mizoroki-Heck arylation in 37%~68% isolated yields at reflux temperature. Their structures were characterized by IR, 1H, 13C NMR, HR-ESI-MS data and X-ray diffraction.

Key words: (E)-3-aryl-7-methylocta-2,6-dienoic acid, Mizoroki-Heck arylation, configuration, synthesis
