The 2-oxospiro[4.5]decan-1-one (or spiro-γ-lactone) structural motif is contained within a number of natural products, for example, the clerodane family of diterpenes. Methods to construct this structural motif are somewhat limited and usually involve multiple functional group interconversions. A novel synthetic approach to this system utilising 6π-electrocyclisation has been identified and associated
