Hyperbranched polyethylenimine derivatives were successfully employed as catalyst
in the Henry reaction. The nitroalcohol products were obtained in excellent yields
within short reaction times. A one-pot synthesis of β-nitrostyrenes was developed
by using ZnCl2 along with hyperbranched polyethylenimine derivatives.
Key words
Henry reaction - diastereoselectivity - polyamine - homogeneous catalysis - β-nitrostyrene
