Resumen
A new method for the synthesis of 1-pyridin-3-yl-β-carboline derivatives involving an intramolecular radical
reaction in the presence of tris(trimethylsilyl)silane and azobisisobutyronitrile (TTMSS/AIBN), via a sultam
intermediate, which proceeds as a one-pot process by ring opening and SNAr substitution, is described.
