(1) Oxidation of dl-α-terpineol with tert-butyl chromate yeilded 8-hydroxypiperitone, which has not previously been described, 8-hydroxycarvotanacetone and homoterpenyl methyl ketone. In this case the oxidative fission of the double bond in the ring took place to a remarkable extent.(2) Oxidation of dl-α-terpinyl acetate with tert-butyl chromate gave 8-acetoxypiperitone, 8-acetoxycarvotanacetone, (neither have previously been described) and homoterpenyl methyl ketone. In this oxidation the cleavage of the ethylenic linkage was suppressed, and the yield of 8-acetoxycarvotanacetone was relatively good.Moreover, the effects of the solvent, acetic acid, benzoyl peroxide, air and the reaction temperature, on the yield of 8-acetoxycarvotanacetone wre investigated.(3) 8-acetoxycarvotanacetone was converted into dl-carvone when acetic acid was eliminated by pyrolysis.(4) The synthesis of carvone from α-terpinyl acetate was attiained through the intermeidate of 8-acetoxycarvotanacetone The overall of carvone from α-terpinyl acetate was 28% mole%.
(1) 用铬酸叔丁酯氧化 dl-α-松油醇,产生了以前从未描述过的 8-羟基哌啶酮、8-羟基香芹烷丙酮和均三萜甲基酮。(2)用铬酸叔丁酯氧化醋酸 dl-α-叔品酯,可得到 8-乙酰氧基哌啶酮、8-乙酰氧基香芹酮(以前均未描述过)和均质甲基酮。此外,还研究了溶剂、醋酸、过氧化苯甲酰、空气和反应温度对 8-acetoxycarvotanacetone 收率的影响。(4) 通过 8-acetoxycarvotanacetone 的中间产物获得了由α-松油基乙酸酯合成卡酮的方法。
