Summary1. The oxidation of cembrene with chromium trioxide in aqueous sulfuric acid (the Jones reagent) and in aqueous acetone has given norcembra-2,7,11-trien-4-one, norsolanadione, (3E, 8E)-5-isopropyl-8-methyltrideca-3,8-diene-2,12-dione, and five new compounds the structures of which have been established on the basis of their spectra.2. Oxidation with chromium trioxide in aqueous acetone, in contrast
总结1. 在
硫酸水溶液(琼斯试剂)和
丙酮水溶液中用
三氧化铬氧化 Cembrene 得到norcembra-2,7,11-trien-4-one,norsolanadione, (3E, 8E)-5-isopropyl-8- 2.甲基trideca-3,8-diene-2,12-dione 等5种新化合物的结构已经确定。 2.在
丙酮水溶液中用
三氧化铬氧化,与用琼斯试剂氧化相反,是立体定向的——塞布烯的 C11-C12 双键不受影响。
