Abstract: Epoxycedrane was firstly synthesized at home and abroad from α-cedrene by epoxidation of hydrogen peroxide under the catalysis of ruthenium trichloride and pyridine-2,6-dicarboxylic acid. The optimal conditions for synthesis of epoxycedrane were 1.90% of ruthenium trichloride,12.28% of pyridine-2,6-dicarboxylic acid, 8 times (equiv) of hydrogen peroxide, 20 h and 30℃.This method not only operates simply and reacts warmly,but also realize 100% conversion of α-cedrene and 84% selectivity of the target product.

Key words: α-cedrene, epoxycedrane, ruthenium trichloride, hydrogen peroxide, pyridine-2, 6-dicarboxylic acid
