Abstract (en)
[origin: WO2006102387A1] An improved process is described for preparing (disubstitutedpropenyl) phenylalkyl substituted dihydrobenzoforans. This improved process is focused on steps to produce key intermediates, namely substituted phenolylalkyl substituted dihydrobenzofurans of formula (I) where R<SUP>3</SUP>, R<SUP>4</SUP>, R<SUP>5</SUP>, R<SUP>6</SUP> and x are defined herein.
