摘要:
1 beta,3 beta,25-Dihydroxy-19-norvitamin D-3 (4a) and 1 alpha,3 alpha,25-dihydroxy-19-norvitamin D-3 (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 H-1-NMR and nuclear Overhauser effect (NOE) experiments.
