alpha-difluoroalkyl)phosphonates were obtained after selective esterification and deprotection of the corresponding phosphonates. These compounds are novel phosphatase-resistant analogues of lysophosphatidic acid and phosphatidic acid. [reaction: see text]
使用手性salen-Co络合物水解1,1-二氟-3,4-环氧丁基膦酸酯的水解动力学拆分为关键步骤,以99%ee作为关键中间体获得对映体二醇。在对相应的膦酸酯进行选择性酯化和脱保护之后,获得对映体均质的(α,α-二氟烷基)膦酸酯。这些化合物是溶血磷脂酸和磷脂酸的新型抗磷酸酶类似物。[反应:看文字]
