Reactions of 4-dialkylamino-5-methoxy-1,2-benzoquinones in acidic media: Selective C-alkylation or N-dealkylation

4-(N-methyl-alkylamino)-5-methoxy-1,2-benzoquinones 3, for which N-alkyl group R1 can give rise to a stabilized carbonium ion, undergo selective acid-catalyzed rearrangements to 3-alkylated-1,2-benzoquinones 4. Aziridino- quinone 10c gives rise to the heterobicyclic 1,2-benzoquinone 11. When R1 does not contain groups capable of stabilizing a positive charge, efficient and selective N-dealkylations occur. The mechanisms of these reactions are discussed.
