Volume 3, Issue 3, pp. 180-282,Serial No. 8 , July 2015, , Pages 208-217

Abstract
  A highly efficient, simple and clean solvent-free protocol for the synthesis of polyhydroquinolines is described. The one-pot multi-component condensation reaction between arylaldehydes, dimedone (5,5-dimethylcyclohexane-1,3-dione), β-ketoesters and ammonium acetate in the presence of catalytic ...  Read More
