RESUMO
Aldose sugars undergo smooth coupling with enamines, generated in situ from aryl amines and 1,3-diketones, in the presence of 10 mol % of InCl3 in water at 80 degrees C to furnish annulated pyrrole derivatives in relatively good to high yields. The use of InCl3, in combination with water, makes this procedure quite simple, more convenient, and environmentally friendly.
