Abstract
Cedrane-8,9-diol( 1H-3a,11-Methanoazulen-8,9-diol,octahydro-2,6,6,8-tetramethyl) was synthesized from cedrene by peroxidation and hydration reactions in one pot,and the total yield was 52. 5 %. Then the white needle crystal was produced by the process of settlement,vacuum distillation,crystallization and recrystallization. The GC content of cedrane-8,9-diol in the crystal was 99. 3 %. The relative molecular weight and the molecular formula were determined by method of element analysis and mass spectrum( MS). The main peaks of Infrared spectrum( IR) showed that,there was no carbonyl group in the molecular structure of cedrane-8,9-diol,but there was two adjacent hydroxyls in it. The main high m / z ion peaks and low m / z ion peaks produced from the title compound by MS could be reasonably interpreted according to the raw materials and synthesis reaction mechanism. The MS detection results showed that the title compound has the same carbon skeleton with cedrene. The protons in the compound were exactly attached by1H NMR spectrum,and the molecule's structure was determined.
