The synthesis and intramolecularDiels-Alderreactions of a series of silyl acetal-tetheredtrienes 4–9 are described. The cycloadditions show complete regioselectivity, and in all but one case give exclusively cis-fused bicyclic products. The selectivities are rationalised in terms of stereoelectronic and steric effects.
