Bibliography: leaves 184-191.In the first phase of this investigation, the synthesis of triene systems, linked via a diester tether was investigated with the aim of studying the respective thermal Intramolecular Diels-Alder (IMDA) properties. It was envisaged that the diene and dienophile would be linked via a conformationally restricted spacer, trans-cyc1ohexane-l,2-dicarboxylic acid anhydride
