α-(Methylene)alkanoic esters are prepared in high yields by substitution of α-(acetoxymethyl)acrylates using Grignard reagents in the presence of a catalytic amount of copper(I) salt. This reaction can be applied to lithium enolates of esters and ketones and to give functional α-(methylene) alkanoic esters, products of great interest for the synthesis of active biological compounds (sarkomycin, α-(methylene)
