The invention relates to methods for producing substituted acrylic acid esters and to the use of the latter for producing substituted γ-amino acids, such as gabapentin and pregabalin. The substituted acrylic acid esters are produced by Wadsworth-Emmons olefination with trialkyl phosphonoacetate in the presence of alkali carbonate as the base, in an aqueous solvent.
本发明涉及制备取代丙烯酸酯的方法,以及利用后者制备取代γ-氨基酸,例如加巴喷丁和普瑞巴林。所述取代丙烯酸酯是通过在水溶剂中以三烷基膦酸乙酯为沃尔茨沃思-艾蒙斯烯化试剂,在碱性碳酸盐存在下作为碱催化剂进行制备的。
