Abstract

Tetralones 3 and 9 on treatment with a mixture of boron trifluoride etherate and acetic anhydride underwent molecular transformations yielding the fully aromatized products 6 and 10, respectively, Oxidation of dimethoxy tetralin 13 with chromic acid and acetic acid afforded 6‐methoxy‐α‐tetralone 12.
