(3RS,4RS)-2-Methyl-3,4-diphenyl-5-hexen-3-ol

The minor diastereomer ([gamma] adduct) of the tertiary homoallylic alcohols, formed in the Zn-mediated reaction between 2-methyl-1-phenyl-1-propanone (isobutyrophenone) and 3-chloro-1-phenylpropene (cinnamyl chloride) in tetrahydrofuran/NH₄Cl(aq), was isolated and crystallized. The structure of the title compound,C₁₉H₂₂O, confirms that the major and minor diastereomers of the [gamma] adduct formed in the reaction have syn and anti configurations, respectively.
