Lactones are utilized in the production of fragrant compositions and flavor complexes for the cosmetic and food industry. This work reports on a three-step lactone synthesis: 1. Aldol condensation of an aldehyde and cyclic ketone catalysed by hydrotalcite. 2. Hydrogenation of the C=C bond in 2-alkylidenecycloalkan-1-one catalyzed by a metal on hydrotalcite support. 3. Oxidation of 2-alkyl¬cycloalkan-1-one catalysed by modified hydrotalcite. All the steps gave high yields.
