Abstract

The synthesis of new C2 symmetric bis(pyrrolidine-triazole)-based organocatalysts and their utility in the asymmetric Michael reaction of β-nitrostyrenes with very high diastereo- and enantioselectivity in water without any additives is reported. The asymmetric synthesis of nitrochromenes is also illustrated.
