New general and operationally simple method for preparation of racemic diethyl α-fluoro-β-ketophosphonates has been developed. Addition of LDA to solution of diethyl fluoromethylphosphonate and aromatic, heteroaromatic and aliphatic esters in THF at −78 °C afforded the corresponding diethyl α-fluoro-β-ketophosphonates in good to high yields.
已经开发了用于制备外消旋α-氟-β-酮膦酸二乙酯的通用且操作简单的新方法。在-78℃下,将LDA加入到氟甲基膦酸二乙酯和芳族,杂芳族和脂族酯在THF中的溶液中,以良好或高收率得到相应的α-氟-β-酮膦酸二乙酯。
