The oxidation of (+)-3-carene with t-butyl chromate was found to afford 3, α-dimethylstyrene (2), eucarvone (3), 1, 1, 4-trimethylcyclohepta-2, 4-dien-6-one (4), 3-methylacetophenone (5), 8-hydroxy-m-cymene (6), car-3-en-2-one (7),(−)-car-3-en-5-one (8), and (−)-car-3-ene-2, 5-dione (9). The aromatized compound (6) was a major product in the oxidation in an acidic medium, whereas the oxidation in the neutral and the basic media gave the enedione (9) ...
