  (R)-7-((1R,3aR,4S,7aR)-4-Hydroxy-7a-methyl-octahydro-inden-1-yl)-2,2-dimethyl-octan-3-one 在 重铬酸吡啶 、 正丁基锂 、 四丁基氟化铵 作用下， 以 四氢呋喃 、 正己烷 、 二氯甲烷 为溶剂， 反应 23.0h， 生成 (R)-7-{(1R,3aS,7aR)-4-[2-((3R,5R)-3,5-Dihydroxy-cyclohexylidene)-eth-(E)-ylidene]-7a-methyl-octahydro-inden-1-yl}-2,2-dimethyl-octan-3-one

  名称：

  Highly antiproliferative, low-calcemic, side-chain ketone analogs of the hormone 1α,25-dihydroxyvitamin D3

  摘要：

  A series 2a-4b of seven new side-chain ketone analogs of calcitriol (1) have been prepared. Unexpectedly, several of these 24- and 25-tert-butyl ketones, even though lacking the classical side-chain tertiary hydroxyl group, are considerably more antiproliferative in vitro than the hormone calcitriol (1) even at physiologically relevant low nanomolar concentrations and are less calcemic than calcitriol (1) in vivo. In addition, ketone analog 19-nor-2a is not significantly less calcemic in vivo than 19-methylene analog 2a. (c) 2005 Elsevier Ltd. All rights reserved.
