  A Concise and Efficient Route to 2α-(ω-Hydroxyalkoxy)-1α,25-dihydroxyvitamin D₃:  Remarkably High Affinity to Vitamin D Receptor¹

  摘要：

  [GRAPHICS]A convenient and potentially valuable synthetic approach to the novel 2 alpha-functionalized 1 alpha,25-dihydroxyvitamin D-3 [1 alpha,25(OH)(2)D-3] derivatives (1a-c), which are the C2-epimer of ED-71 and its analogues, has been developed. The C2 alpha-modified ring A precursors (1,7-enynes 16, n = 0, 1, and 2) were constructed stereoselectively starting from D-glucose in high yield. In the synthesized 2 alpha-(omega-hydroxyalkoxy)-1 alpha,25(OH)(2)D-3 derivatives, la and Ib showed a greater binding affinity to vitamin D receptor (VDR), up to 1.8 times that of the native hormone.
