    1β,3β,25-Dihydroxy-19-norvitamin D3 (4a) and 1α,3α,25-dihydroxy-19-norvitamin D3 (4b) were synthesized by employing a new A-ring synthon, (1R,3S)-3-((tert-butyldimethylsilyl)oxy)-5-oxocyclohexyl benzoate (19), which was derived from D-(-)-quinic acid in 12 steps. The A-ring was coupled with the circular dichroism (CD) ring by means of Julia-Kocienski olefination to construct the diene unit. The structures of the products were confirmed by 1H-NMR and nuclear Overhauser effect (NOE) experiments.
