Two vitamin D3 derivatives, namely 24,24-difluoro-1β,3β,25-dihydroxy-19-norvitamin D3 (6a) and 24,24-difluoro-1α,3α,25-dihydroxy-19-norvitamin D3 (6b), were synthesized via a convergent route employing Julia-Kocienski olefination as a key step. Compounds 6a and b bound to vitamin D receptor (VDR) with IC50 values of 64.8 and 57.6 nM, respectively, exhibiting about 400- and 30-fold greater binding affinity than the corresponding non-fluorinated derivatives 5a and b.
