Sulfinyltoluquinones (2a–2c) were submitted to thermal or catalyzed [4+2] cycloaddition reactions with cyclopentadiene. For p-tolylsulfinyltoluquinones (2b) and (2c), almost complete C2–C3-chemo- and unlike-diastereoselectivity was achieved by catalysis with ZnBr2, yielding adducts 6. Under thermal conditions, Diels–Alder reaction took place at the C5–C6 double bonds of quinones 2a–2c, generating mixtures of diastereoisomeric like- and unlike-adducts 4.
