## Abstract 4,9‐Dimethoxynaphtho[2,3‐__b__]furan 9 was obtained in 91% yield __via__ the reductive methylation of naphtho[2,3‐__b__]furan‐4,9‐dione 2. After treatment of 9 with butyllithium, the mixture was allowed to react with __N,N__‐dimethylacetamide, followed by oxidization with cerium(IV) dia
