Ethyl E,E-6-(ethoxycarbonylmethyl)cyclodeca-1,6-dienylacetate is shown, by NMR spectroscopic evidence, to exist primarily in the boat conformation at room temperature.

cyclodecyl derivatives with functionalisation on the ends of two-carbon side-chains at both the 1 and 6 positions have been prepared starting from 6-hydroxycyclodecanone 6. Key intermediates to these compounds were the mixture of alkenes obtained by dehydration of ethyl E-6-(ethoxycarbonylmethyl)-1-hydroxycyclodec-5-enylacetate 18 and those obtained from the ethyl 6-(ethoxycarbonylmethyl)-1-hydroxycyclodecylacetates
