A concise synthesis of naphthalene compounds for incorporation into a synthetic sequence for the rubromycin family of natural products is presented. These highly substituted naphthalenes are generated in seven and nine steps, respectively, from 2,4,5-trimethoxybenzaldehyde. Three ring-forming methods were explored and the controlled oxygenation of different positions was investigated to yield differentially
提出了一种萘化合物的简明合成方法,该方法可掺入天然产物红霉素家族的合成序列中。这些高度取代的萘分别由2,4,5-三甲氧基苯甲醛分七个步骤和九个步骤生成。探索了三种成环方法,并研究了不同位置的受控氧合以产生差异取代/受保护的系统。最终产品的关键步骤包括Stobbe缩合反应形成环系统,以及一系列新的区域选择性氧化反应,以引入所需的氧官能度。这些萘产物包含正交保护基,适合与各种偶联剂结合使用。
