The reaction of carvomethene oxide (a mixture of <I>cis</I>- and <I>trans</I>-forms) over solid acids and bases gives <I>trans</I>-and <I>cis</I>-1-methyl-3-isopropyl-1-cyclopentanecarbaldehyde (III), carvomenthone (IV), 1(7)-<I>p</I>-menthen-2-ol of <I>trans</I>-(V) and <I>cis</I>-form and carvotanacetol of <I>trans</I>-(VI) and <I>cis</I>-form. A large amount of III was formed together with IV over SiO<SUB>2</SUB>–Al<SUB>2</SUB>O<SUB>3</SUB>, SiO<SUB>2</SUB>–TiO<SUB>2</SUB> and zeolite H-F9. LiClO<SUB>4</SUB>, H<SUB>2</SUB>SO<SUB>4</SUB>/SiO<SUB>2</SUB>, FeSO<SUB>4</SUB>, and solid H<SUB>3</SUB>PO<SUB>4</SUB> gave preferentially IV, while TiO<SUB>2</SUB>-ZrO<SUB>2</SUB> formed mainly V and VI. With respect to aluminas, carbonyl compounds (III and IV) were predominantly formed over Al<SUB>2</SUB>O<SUB>3</SUB>D, while allylic alcohols (V and VI) were preferentially given by Al<SUB>2</SUB>O<SUB>3</SUB> A and B.
