Diene moieties conjugated to a carbonyl group are ubiquitous in nature and are present in compounds with relevant biological properties. Herein we investigate the cross metathesis (CM) of the renewable cross partners estragole and methyl sorbate (MeSo) to produce methyl 6-(4-methoxyphenyl)hexa-2,4-dienoate. By the judicious choice of the ruthenium-based metathesis catalysts, as well as the reaction conditions, it was possible to obtain good conversion and selectivity for the desired product in catalyst loadings as low as 50 ppm (0.005 mol%), with a minimal amount of solvent.
A NOVEL APPLICATION OF MOLYBDENUM MEDIATED DIENE SYNTHESIS IN THE PREPARATION OF PIPEROVATINE

A novel regio- and stereoselective synthesis of the dienamide piperovatine is described.This method does not suffer from problems associated with doublebond migration.
