Pyrido[l,2-u]benzimidazoles are prepared by hypervalent iodine C-H cycloamination of N-aryl-2-aminopyridines (Scheme 49) (13T10739).The reaction tolerated both electron-donating (OMe, Me, f-Bu) and electron-withdrawing groups (halides, nitro) on the aniline. However, sterics appears to slow the reaction as the yields were poor (9-23%) with same functional groups when placed ortho rather than para. A number of substituents (Me, halides, esters, CF3) were also tolerated on the pyridine ring. Quinolines and isoquinolines also reacted smoothly under these conditions. [Pg.375]
