文摘The enantioselective total synthesis of 12 carboxyeudesma 3,11(13) diene(1) was achieved starting from(-) dihydrocarvone in ten steps for the first time. The key steps mainly include the introduction of hydroxyl group into C 12 position of eudesmane by Vilsmeier chlorination and the generation of C3-C4 double bond into the eudesmane skeleton by elimination of halide.
