A method for producing α-substituted acrylate esters is provided which can be suitably used as an industrial method for producing α-substituted acrylate esters because the method does not have problems of apparatus corrosion or does not require waste detoxification and allows reaction in a short time with high yield. The method for producing an α-substituted acrylate ester includes a step of carrying out a reaction of a compound having a specific structure and an active hydrogen-containing compound under a condition where a tertiary amine and an acid and/or a salt thereof coexist.

catalyst system for the catalytic DA reaction of less reactive α,β-unsaturated lactone derivative with cyclopentadiene (CP). In this catalyst system, Tf2CHAlMe2 is an active species and an excess amount of Me3Al plays an important role to lower the catalyst loading. Substituent effect of the lactone framework on π-facial selectivity was also examined. In the reactions of both γ-substituted 5-membered lactone
