A general and simple methodology for spirocyclopentannulation of cyclic ketones (or 4,4-disubstituted cyclopentenones from acyclic ketones) and its application in the synthesis of the spirodienone via a prochiral precursor constituting a formal totalsynthesis of (±)-acorone (), are described.

Irradiation of 4-aryl-4-alkylhex-5-en-2-ones (e.g. ) or 5-aryl-4-alkylhex-5-en-2-ones (e.g. ) adsorbed on montmorilloniteK-10 in a commercial microwave oven furnishes the multialkylated naphthalenes (e.g. ).
