The convergent synthesis of ardisiaquinones D (1), E (3) and F (4), isolated as 5-lipoxygenase inhibitors from Ardisia sieboldii, has been achieved efficiently by a cross-coupling reaction via an acetylene between two benzene units bearing appropriate functional groups readily derived from 2, 5-dimethoxy-1, 4-benzoquinone.
通过交叉耦合反应,在容易从 2,5-二甲氧基-1,4-苯醌衍生出的带有适当官能团的两个苯单元之间通过乙炔有效地合成了从西波胆蒿中分离出的 5-脂氧合酶抑制剂--西波胆蒿醌 D (1)、E (3) 和 F (4)。
