Studies on Organic Fluorine Compounds. XXXIX. Studies on Steroids. LXXIX. Synthesis of 1α, 25-Dihydroxy-26, 26, 26, 27, 27, 27-hexafluorovitamin D3
Yoshiro Kobayashi,Takeo Taguchi,Satoshi Mitsuhashi,Tadashi Eguchi,Etsuo Ohshima,Nobuo Ikekawa +5 more
TL;DR: 1α, 25-Dihydroxyhexafluorovitamin D3, via the corresponding 5, 7-diene, was synthesized by two procedures as discussed by the authors, which consisted of construction of the hexafluoro-25-hydroxy part on the side chain followed by the introduction of a hydroxy group at the 1α-position.
