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
