✦ Synopsis

Switching Selectivity in o-Benzoquinone Cycloadditions. -Whereas the methoxy-substituted o-benzoquinone (II), like other unsaturated ketones, acts as a dienophile in the reaction with the enantiopure cyclopentadiene (I), the corresponding alkyl-substituted o-benzoquinones (IV) behave as an electron-poor 4π-system.
