The absolute configuration of natural phylloquinone (vitamin K,) (I) isolated from alfalfa has been determined. The 7′R and 11′R configurations have been derived from the optical rotatory dispersion curves of (6R, lOR)-6,10,14-trimethyl pentadecanone (11) obtained from natural phylloquinone as well as from natural (7R,11R)-phytol (IV).
已经确定了从苜蓿中分离出的天然叶醌(
维生素K,)(I)的绝对构型。7'R和11'R构型是根据从天然叶醌和天然(7R,11R)获得的(6R,10R)-6,10,14-三甲基
十五烷酮(11)的旋光色散曲线得出的-
植醇(IV)。
