New methods for C-N bond construction exploiting the N-centered electrophilic character of iminoquinones were reported. Iminoquinones, generated in situ via the condensation of o-vinylanilines with benzoquinones, underwent acid-catalyzed cyclization to afford N-arylindoles I [R = H, F; R1 = H, Me, Ph, etc.; R2 = H, Me; R3 = H, Cl, CO2Me, etc.; Ar = 3,5-di-(t-Bu)-4-OHC6H2, 3,5-di-Me-4-OHC6H2, 3,5-di-(t-Bu)-2-OHC6H2, 10-hydroxy-9-phenanthryl] in excellent yields. Under similar reaction conditions, homoallylic amines reacted analogously to afford N-arylpyrroles II [R4 = Ph, 3-MeOC6H4, 4-FC6H4, 2,6-di-FC6H3, 2,3-dihydrobenzofuran-5-yl; R5 = H, 4-MeC6H4; Ar = 3,5-di-(t-Bu)-4-OHC6H2]. Addnl., organometallic nucleophiles were shown to add to the nitrogen atom of N-alkyliminoquinones to provide amine products. Finally, iminoquinones were shown to be competent electrophiles for copper-catalyzed hydroamination.
