Reaktionsschritte
By following the procedure of D. T. Warner, cited above, used for preparing diethyl 2-formylcyclopropane-1,1-dicarboxylate from acrolein but using equivalent amount of dimethylbromomalonate and methanol instead of diethylbromomalonate and ethanol, respectively, the title compound, nmr (CDCl3) δ 1.98 (m,2H), 2.80(m, 1H), 3.79(s,6H), 8.82(d, J = 4 cps, 1H), is obtained.
