A regioselective cyclohexannulation procedure, whose key step involves the [4 + 2] cycloaddition of dienamines 12–24 with methyl acrylate, allows the conversion of cycloalkanones 1–11 to bicyclic dienoates 25 – 37. The chemistry of 26 is briefly examined and, in the context of organoleptic studies concerning functionalised 5,5,9-tri-methyldecalins, the transformation of 37 to ketones 44 and 46 as well
