A facile efficient approach to the 2-styrylmalonates via the Lewis acid-catalyzedisomerization of 2-arylcyclopropane-1,1-dicarboxylates has been developed. The efficiency of this method was demonstrated for a representative series of such cyclopropanes. The isomerization proceeds chemo-, regio- and stereoselectively to afford E-styrylmalonates in good yields.
