Diels-Alder reaction. This procedure proved very versatile, fast, and with an easy workup step, and therefore suitable even for large-scale synthesis. Diels-Alder reactions - bicyclic compounds - cycloadditions - norbornene - microwave - polychlorinated norbornanes

base‐mediated formation of a bridgehead double bond in a bicyclo[2.2.1]heptane system (anit‐Bredt molecules) is described. The synthesis of exocyclic norbornyl enones by Wittig reaction of α‐diketones is reported. These enones and their Michael adducts are used as substrates for the generation of transient bridgeheadenones and their trapping with MeOH and H2O. Bridgehead alcohols are easily synthesized
