The ultimate metabolite of vitamin K, 2-methyl-3-(3′,3′-carboxymethylpropyl)-1,4-naphthoquinone (1), has been shown to be biologically active and may be used as a measure of vitamin K levels in the body. We report a facile, five-step synthesis of 1 that requires only two isolated intermediates and a single chromatographic purification, and provides the title product in 26% overall yield. The structure
维生素K的最终代谢物2-甲基-3-(3',3'-羧甲基丙基)-1,4-萘醌(1)具有生物活性,可以用作维生素K水平的量度在身体里。我们报告了一种简便,五步合成1的方法,该方法仅需要两个分离的中间体和一次色谱纯化,即可提供标题产物,总收率26%。中间体之一的结构通过X射线晶体学确认。
