sugar-oxasteroid-quinone hybrid molecules. For the synthesis of series of sugar-oxasteroid-quinone hybrid analogues, 1, 2, 5, 6-diisopropylidine-D-glucose was chosen as the chiral pool starting material. A range of sugar derived enynes are synthesized from a common precursor and their treatment with various quinone dienophiles in Diels-Alder reaction conditions resulted in a library of sugar-oxasteroid-quinone
本文报道了顺序烯炔复分解/ Diels-Alder策略合成了有趣的一类糖-氧杂甾体-醌杂化分子。为了合成一系列糖-氧杂甾体-醌杂合类似物,选择1、2、5、6-二异丙基吡啶-D-葡萄糖作为手性库起始原料。从常见的前体中合成了一系列糖衍生的烯炔,并在Diels-Alder反应条件下用各种醌二烯亲和剂对其进行了处理,形成了糖-氧杂甾体-醌杂化物库
