Sodium azide reacts regiospecifically with the ortho‐NO2 group of 2,4‐dinitrostilbenes (I) to provide the 2‐amino‐4‐nitrostilbenes (II) as the sole products in good yields.
Direct Arylation of Electron-Poor Indolizines. -The direct Pd-catalyzed arylation of indolizines (III) bearing at least one electron-deficient substituent at positions 1 and 2 is demonstrated. Similar conditions allow bis-arylation of an 2-arylindolizine for the first time. -(KOSZARNA, B.; MATCZAK, R.; KRZESZEWSKI, M.; VAKULIUK, O.; KLAJN, J.; TASIOR, M.; NOWICKI, J. T.; GRYKO*, D.
