Description |
A green and efficient multicomponent one-pot synthesis of Hantzsch polyhydroquinoline was achieved by
the condensation of aldehydes, dimedone, ethylacetoacetate and ammonium acetate at room temperature
using environmentally benign modified Montmorillonite supported Ni0-nanoparticles as catalyst. The well
dispersed Ni0-nanoparticles having a high surface to volume ratio have promising features for the reaction
such as easy removal of the catalyst, solvent-free, shorter reaction time, high product yields (about 95%)
and easy work up procedure. There is no significant effect of electron withdrawing or donating nature of
substituent on aldehydes in the formation of polyhydroquinoline derivatives.
