DIELS-ALDER REACTION OF TETRACYCLONE WITH SOME MALEIMIDES

DIELS-ALDER REACTION OF TETRACYCLONE WITH SOME MALEIMIDES

Tetracyclone I reacts with N-substituted maleimides II to give the adducts III a–f. Dehydrogenation of III c, e, f gave IV a–c. In a similar manner III adds another molecule of either maleic anhydride or N-substituted maleimide to give V a–b and VI a–e respectively. On the other hand, VI b dehydroge...

Zusammenfassung:Tetracyclone I reacts with N-substituted maleimides II to give the adducts III a–f. Dehydrogenation of III c, e, f gave IV a–c. In a similar manner III adds another molecule of either maleic anhydride or N-substituted maleimide to give V a–b and VI a–e respectively. On the other hand, VI b dehydrogenates readily to VII.
