The first domino ‘2 : 1 condensation/intramolecular aldol’ reactions of 1,3-bis(trimethylsilyloxy)-1,3-butadiene with tetraalkoxymethanes provide a convenient approach to 3-hydroxy-5-alkoxyhomophthalates. These products, which contain one free and one protected hydroxyl group, can be functionalized by palladium(0)-catalyzed cross-coupling reactions.
