(R)-and (S)-N,N-Diethyl 2,2-difluoro-3-(2-furyl)-3-hydroxypropionamide 7 have been obtained via enzymic resolution of the racemic acetate using lipase MY from Candida cylindracea. Ozonolysis of the (S)-7 followed by hydrolysis afforded the (S)-β,β-difluoromalic acid 1.
(R)-和(S)-N,N-
二乙基2,2-二
氟-3-(2-
呋喃基)-3-羟基丙酰胺7已经通过使用
脂肪酶MY对消旋
乙酸酯进行酶促拆分而获得,其来自假丝酵母。将(S)-7进行
臭氧分解,然后
水解,得到(S)-β,β-二
氟苹果酸1。
