The Claisen rearrangement of 1-methyl-2-[(3-methylphenoxy)methyl]cyclopentene in <I>N</I>,<I>N</I>-dimethylformamide gave 5-methyl-2-(1-methyl-2-methylenecyclopentyl)phenol(<B>5</B>) <I>via</I> its trimethylsilyl ether. The methylation of <B>5</B>, followed by a Simmons-Smith reaction and by the catalytic hydrogenolysis, afforded 3-hydroxycuparene.
