H. Togo et al., CYCLIC AMINATION ONTO AROMATIC RING VIA RADICAL PATHWAY WITH (DIACETOXYIODO)ARENES, Phosphorus, sulfur and silicon and the related elements, 120, 1997, pp. 449-450
Sulfonamides of primary amine bearing an aromatic ring at gamma-positi
on were treated with (diacetoxyiodo)arene and iodine under irradiation
conditions with a tungsten lamp to give the corresponding 1,2,3,4-tet
rahydroquinoline derivatives in moderate to good yields.
