Silaketals, in which reactive dienes and dienophiles are linked, can participate in intramolecular Diels-Alder reactions to produce products with a high degree of stereocontrol and with regiochemistry opposite to that predicted by bond polarization models.

## Abstract The utility of the readily available asymmetric 1,3‐dioxane template in intramolecular Diels–Alder reactions is reported. The 1,3,9‐decatrienoates substrates gave predominantly the __endo__‐boat products, with minor amounts of the __exo__‐boat isomer. Various substitutions (14 examples)
