A method of reducing an aromatic ring or a cyclic, allylic ether in a compound includes preparing a reaction mixture including a compound including an aromatic moiety or a cyclic, allylic ether moiety, an alkali metal, and either ethylenediamine, diethylenetriamine, triethylenetetramine, or a combination thereof, in an ether solvent; and reacting the reaction mixture at from −20° C. to 30° C. for a time sufficient to reduce a double bond in the aromatic moiety to a single bond or to reduce the cyclic, allylic ether moiety.
isomerization and Diels-Alderreaction of 2,5-dihydroanisoles are presented. Some of the further chemistry of the products is detailed. The in situ generation, and further reactions of 2,3-dihydroanisoles by the pyrolysis of 2-methoxy-1,4-dihydrobenzoic acids is described. This technique constitutes a route to certain cyclohexadienes otherwise difficult of access. The in situ isomerization and Diels-Alder reaction
