IntramolecularDiels-Alderreactions of cyclohexane-1,2-dicarboxylic anhydride-derived diester-tethered trienes are described. The stereoselectivities of most of the cycloaddition processes studied may be rationalised in terms of an preferred ‘inside’-oriented diene giving rise to an endo-transition state.
