Mitt. XV: Struktur und Reaktivitaet von isoanellierten heterocyclischen Systemen mit 4n?- und (4n + 2) ?-Elektronen. 2-t-Butyl-4-methyl-2,4-dihydropyrroloindole. Reaktionen mit aktivierten CC-Dienophilen

Reactions of 2-t-butyl-4-methyl-2,4-dihydropyrroloindoles with N-aryl-maleimides have been investigated.The formation of 1:1-cycloadducts is influenced by substituents at 1,3-position.The consecutive transformations of these intermediates can be controlled by nucleophilic solvents or reagents.Ring opening reactions occur at the labile N,O-acetal group of the cycloadducts followed by elimination or addition reactions.
