Stereo-electronic effect of partial charge over oxygen atom in prolinol ether catalysts in Michael addition reactions of Propanal to β-Nitrostyrenes

In this article, the utility of the synthesized prolinol derived organocatalysts in the Michael addition reaction of propanal with differently substituted β-nitrostyrenes has been discussed. The effect of the catalyst substitution on the reactivity of the reactions is studied along with the varying reactivity while using different electrophiles (in this case nitrostyrene).
