Synthesis of 8-Methoxy-1-Tetralone

Several methods have been developed for the synthesis of 8-methoxy-1- tetralone 4. The applications of some named organic reactions can be observed during the synthesis of tetralone 4. Attempts have been made to achieve the direct conversion of 5-methoxy-1-tetralone into the tetralone 4. The method for the ring expansion of tertiary cyclobutanol 30 catalyzed by silver salts has proved useful to obtain the title tetralone 4.
