synthetic method for the preparation of C-2 substituted furanonaphthoquinones from ortholithium-benzamide and the 2-furan-carboxaldehyde derivative is described. Four 2-alkyl-furanonaphthoquinones and the 2-phenyl-substituted were prepared via phathalide. This route has been shown to be general application to the synthesis of furanonaphthoquinones.
摘要 介绍了一种以邻锂-苯甲酰胺和2-呋喃-甲醛衍生物为原料合成C-2取代呋喃萘醌类化合物的方法。四个 2-烷基呋喃萘醌和 2-苯基取代的化合物是通过 phathalide 制备的。该路线已被证明是合成呋喃萘醌的普遍应用。
