A new fluorinated analog of vitamin D2, 24-epi-26, 26, 26, 27, 27, 27-hexafluoro-1α, 25-dihydroxyvitamin D2, was efficiently synthesized starting from (R)-4-isopropyl-3-propionyl-2-oxazolidinone with high stereochemical control.In all four physiological test systems, the fluorinated vitamin D2 analog was found to be slightly less active than 1α, 25-dihydroxyvitamin D3.
以(R)-4-异丙基-3-丙酰基-2-噁唑烷酮为起始原料,高效合成了一种新的氟化维生素 D2 类似物,即 24-表-26、26、26、27、27-六氟-1α,25-二羟基维生素 D2。
