Since S-(+)-2-methylglutaric acid (V) and S-(-)-4-hydroxyvaleric γ-lactone were obtained by degradation of an α, β-unsaturated ketone (II) derived from guaiol (I), the configurations of the methyl groups at C-4 and C-10 in guaiol are both α-oriented and guaiol should be represented by (XII). Further, from these results the stereochemistry of four isomeric nepetalinic acids and iridolactones was elucidated.
