Abstract :
The title compounds form Diels–Alder cycloadducts with a number of dienes, which can be transformed into vic-bromo(trimethylstannyl)olefins, ultimate precursors for the synthesis of benzocyclotrimers via copper-mediated cyclotrimerization. The overall result is a formal condensation of three diatomic carbons with three dienes.
