A new strategy for the construction of spiro[4,5]decanes is described and involves a bridgehead substitution of a methoxyl group in 6 by a methyl group, followed by an oxidative cleavage resulting in a stereogenic spirocentre which culminated in the formal synthesis of acorone.

Preparation of the key intermediates, 11 and 21, required for the synthesis of (±)-allo-cedrol (khusiol) is reported by a novel methodology involving the substitution at the bridgehead position of 1-methoxybicyclo[2.2.2.]oct-5-en-2-one derivatives.
