  Fluorinated alcohols as solvents for diels-alder reactions of chiral acrylates

  摘要：

  Fluorinated alcohols increase the rates and endo/exo selectivities of the Diels-Alder reactions of cyclopentadiene with (-)-menthyl and (-)-8-phenylmenthyl acrylates. The use of fluorinated alcohols also increases the diastereofacial selectivity in the reactions of (-)-menthyl acrylate, but decreases it when the dienophile is (-)-8-phenylmethyl acrylate. These facts are accounted for by the conformational preferences of the dienophile in non-HBD solvents and by the tendency of fluorinated alcohols to shift the conformational equilibrium towards the s-trans conformation.
