The structures of the diol and the conjugated ketone obtained from the osmium tetroxide oxidation of hopa-15, 17(21)-dienes (I) were now revised and correctly assigned as IV and V, respectively, the former being obtained by lithium aluminum hydride decomposition and the latter by hydrogen sulfide decomposition of the intermediate osmate. Hop-17(21)-ene (VI) was also found to give the seco-diketone (VIII) in lesser yield. A probable mechanism for the formation of the seco-diketones was also discussed.
通过四氧化锇氧化合-15、17(21)-二烯 (I)得到的二元醇和共轭酮的结构现在得到了修正,并正确地分别归为 IV 和 V,前者是通过氢化铝锂分解得到的,后者是通过中间产物 Osmate 的硫化氢分解得到的。研究还发现,Hop-17(21)-烯 (VI) 可以生成仲二酮 (VIII),但产率较低。此外,还讨论了仲二酮的可能形成机理。
