Iodine-mediated intramolecular electrophilic aromatic cyclization in allylamines: A general route to synthesis of quinolines, pyrazolo[4,3-b]pyridines and thieno[3,2-b]pyridines§
An unprecedented synthesis of aromatic ring annulated pyridines from suitably substituted primary allylamines via intramolecular electrophilic aromatic cyclization mediated by molecular iodine under mild conditions is described.
