A novel, efficient, and facile approach for the synthesis of structurally important pyrimidines has been successfully developed by Cu-catalyzed and 4-HO-TEMPO-mediated [3 + 3] annulation of commercially available amidines with saturated ketones. This method provides a new protocol for the synthesis of pyrimidines by a cascade reaction of oxidative dehydrogenation/annulation/oxidative aromatization

Abstract Acetylation of 9‐alkylcarbazoles with acetic anhydride catalyzed by PPh3 · HClO4 was reported to give acetylcarbazoles. Carbazolealdehydes were easily synthesized by the Vilsmeier reaction of 9‐alkylcarbazoles under microwave condition in good yields.
