Reaction Steps

A mixture of cyclobutyl-methanol (8.00 g, 93.02 mmol), ethoxycarbonylmethylene triphenylphosphorane (19.42 g, 55.81 mmol) and pyridine (3 mL) were dissolved in dry chloroform (100 mL) and heated at 70° C. Manganese dioxide (97.11 g, 1.12 mol) was added portion wise over a period of 5 h (with 1 h gap between each addition) and refluxing was continued for 20 h. The reaction mixture was cooled to room temperature, filtered over celite and washed with chloroform. The filtrate was concentrated and the residue subjected to column chromatography over silica gel (60-120 mesh) using 0% to 15% of ethyl acetate in pet ether as eluent to afford ethyl 3-cyclobutylprop-2-enoate (2.10 g, 15%) as a liquid.
