Reduction of α-anilinomethyl-1,2-butenolides with diisobutylaluminium hydride yielded the corresponding 3-anilinomethylfurans. Hydrogenolysis of 3-anilinomethyl-5,6,7,8-tetrahydro-7-methylbenzo[b]furan over 10 % Pd-C afforded (±)-menthofuran. This synthetic way leading to 3-methylfuran derivatives was applied to a synthesis of (±)-laevigatin starting from 4,7-dimethyl-1-tetralone.
