## Abstract Boron tribromide is presented as a highly reactive reagent that __simultaneously__ allows the demethylation and fully diastereoselective cyclization of different precursor molecules, obtained by an aldol‐type reaction, to a series of hydroxylated aryldihydrobenzofuran systems in racemic
