Novel synthesis of 1α,25-dihydroxy-19-norvitamin D from 25-hydroxyvitamin D

19-Norvitamin D analogs 3a and 3b were synthesized from 25-hydroxyvitamin D, obtained via a bioconversion method. The synthetic route features a highly regio- and stereoselective hydroboration reaction to afford 25-hydroxy-3,5-cyclopropyl-vitamin D deriva

Development of an affinity-driven cross-linker: Isolation of a vitamin D receptor associated factor

A vitamin D analogue containing an affinity and a photoaffinity probe (affinity-driven cross-linker, Double Label) was synthesized. An unknown factor, associated with vitamin D receptor (VDR), was isolated from rat liver nuclear extract using a GST-VDR-ligand-binding domain fusion protein (GST-VDR-LBD), affinity labeled with Double Label, and protein-protein cross-linking by photolysis.

Synthesis, conformational analysis, and biological-activity of the 1-α,25-dihydroxy-10,19-dihydrovitamin D3 isomers

The synthesis of the four 1α,25-dihydroxy-10,19-dihydrovitamin D3 stereoisomers (8-11) is described starting from 25-hydroxyvitamin D3(1c). Acetic acid-catalyzed cycloreversion of 1 α-hydroxylated 3,5-cyclovitamin D compound 14, prod

Direct C(1) Hydroxylation of Vitamin D3 and Related Compounds

A direct synthesis of C(1) hydroxylated vitamin D analogues from the corresponding vitamin D precursors has been developed.Allylic oxidation of 3,5-cyclovitamin D derivatives, readily obtained from the buffered solvolysis of vitamin D tosylates, with selenium dioxide yields 1α-hydroxylated 3,5-cyclovitamin D compounds which are smoothly converted to the desired 1α-hydroxyvitamin D derivatives by acid-catalyzed cycloreversion.Application of this scheme to vitamin D3 (1a), 25-hydroxyvitamin D3 (1b), and vitamin D2 (1c) affords the 1α-hydroxy products in ca.20 percent overall yield.
