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-trimethyldecalins, the transformation of 37 to ketones 44 and 46 as well as to acetates 53-56 is described.
