Cyclopentadiene → 2-Hydroxyethyl bicyclo[2.2.1]hept-5-ene-2-carboxylate

Participants

Reaction Steps

Cyclopentadiene (66 g) and 140 g of 2-hydroxyethyl acrylate were dissolved in 500 g of THF solvent. After the reaction at 30° C. for 24 hours, the solvent was removed by rotary evaporator. The residue was distilled under reduced pressure to obtain 148 g of 2-hydroxyethyl 5-norbornene-carboxylate as a mixture of endo and exo (yield: 72%). NMR spectral data of the resulting compound (21) is shown in FIG. 4.
