    Novel 1α,25-Dihydroxyvitamin D3 Analogues with the Side Chain at C12
    摘要:
    The plethora of actions of 1 alpha,25(OH)(2)D-3 in various systems suggested wide clinical applications of vitamin D nuclear receptor (VDR) ligands in treatments of inflammation, dermatological indication, osteoporosis, cancers, and autoimmune diseases. More than 3000 vitamin D analogues have been synthesized in order to reduce the calcemic side effects while maintaining the transactivation potency of the natural ligand. In light of the crystal structures of the vitamin D nuclear receptor (VDR), novel analogues of the hormone 1 alpha,25(OH)2D3 with side chains attached to C-12 were synthesized via the convergent Wittig-Horner approach. Among the compounds studied, the analogue 2b showed the highest binding affinity for VDR and was the most potent at inducing VDR transcriptional activity in a transient transfection assay (20% of the transactivation activity of the natural ligand).

    Ag(I)- or Ag(I)–Au(I)-catalyzed cascade annulation of alkynols (5-hexyn-1-ol systems) with α-ketoesters involving a dual activation process (π and σ) has been developed for the first time. This reaction proceeds through cycloisomerization of alkynol to give the 6-endo-enol ether followed by annulation with an α-ketoester to furnish furo[2,3-b]pyran-2-ones in good yields.
