7-Methoxy-2-tetralone Usage And Synthesis

Chemical Properties

Clear yellow to orange liquid after melting

Uses

7-Methoxy-2-tetralone was used in the synthesis of 2-bromo-3,4-dihydro-7-methoxy-1-naphthaldehyde and 2-substituted octahydrobenzo[f]quinolines.

Flammability and Explosibility

Not classified

Synthesis

2,7-Dimethoxynaphthalene was dissolved in an organic solvent and reacted in the presence of anhydrous ethanol and sodium metal at -20C to 5C to produce intermediate (I). The intermediate (I) was dissolved in an organic ketone solvent (e.g. acetone or cyclohexanone) and then reacted under the condition that the pH of the reaction system was adjusted to 1-3 by dilute hydrochloric acid to obtain 7-methoxy-2-naphthalenemannone.
