A total synthesis of title <I>cis</I>-clerodane diterpene <B>9</B> has been achieved starting from a bicyclic intermediate <B>4</B>, which was developed previously by us. Firstly the compound <B>4</B> was converted by five steps to octalone derivative <B>6</B>, of which angular methylation, with the protection of 3-methylene group, afforded <I>cis</I>-decalone <B>7</B>. Appendage of 3-furyl group and deoxygenation at C-20 carbon atom transformed the compound <B>7</B> to furanoid ketone <B>8</B>. Methylenation of <B>8</B> followed by the double bond isomerization led to the completion of the synthesis.
