Kaempferol (1), a natural product from various plants, was synthesized in which the longest linear sequence is only seven steps in over all yields of 47% from commercially avail able 1,3,5-trimethoxybenzene (10). The methylated kaempferols 2–5 were also pre pared by use of this concise synthetic methodology. The key transformations in this synthesis involved the I2 oxidative-promoting-cyclization and
山奈酚 (1) 是一种来自各种植物的天然产物,其最长的线性序列只有 7 个步骤,从市售的 1,3,5-三甲氧基苯 (10) 的总产率为 47%。甲基化的山柰酚 2-5 也是通过使用这种简洁的合成方法制备的。该合成中的关键转化涉及 I2 氧化促进环化和 DDO 氧化羟基化。提供了实现 1 的几种策略。
