convenient and versatile method was developed for the synthesis of 2,2,2-trifluoroethyl methyl 2-oxoalkylphosphonates starting from dimethyl phosphonates by alkaline hydrolysis followed by esterification with 2,2,2-trifluoroethanol using diisopropylcarbodiimide (DIC) in the presence of 4-(dimethylamino)pyridine (DMAP) catalyst following the Steglich protocol.
图形摘要 摘要 开发了一种方便且通用的方法,从膦酸二甲酯开始,通过碱水解,然后使用二异丙基碳二亚胺 (DIC) 与 2,2,2-三氟乙醇酯化合成 2,2,2-三氟乙基甲基 2-氧代烷基膦酸酯。遵循 Steglich 方案,存在 4-(二甲氨基)吡啶(DMAP)催化剂。
