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
发现 (+)-3-carene 与铬酸叔丁酯氧化得到 3,α-二甲基苯乙烯 (2), eucarvone (3), 1,1,4-trimethylcyclohepta-2,4-dien-6-one (4), 3-甲基苯乙酮 (5), 8-羟基-间-伞花烃 (6), car-3-en-2-one (7), (-)-car-3-en-5-one (8 ) 和 (-)-car-3-ene-2,5-dione (9)。芳构化化合物 (6) 是酸性介质中氧化的主要产物,而中性和碱性介质中的氧化得到烯二酮 (9) 和烯酮 (8) 作为主要产物。此外,证明与 (-)-cis-carane (10) 和 (+)-caran-3β-ol (11) 的环丙烷环相邻的亚甲基几乎不受铬酸叔丁酯的攻击。
