Abstract

A study on the synthesis of the isomers of the natural C-13 norterpenoids derivatives 7, 11- epoxymegastigma-5 (6)-en-9-one and 7, 11-epoxymegastigma-5 (6)-en-9-ols is reported. The latter compounds were prepared from readily available racemic α-ionone and then resolved by mean of lipase-mediated acetylation. The obtained enantiomerically forms were evaluated for their odour properties.
