ChemInform Abstract: Alginic Acid: A Highly Efficient Renewable and Heterogeneous Biopolymeric Catalyst for One-Pot Synthesis of the Hantzsch 1,4-Dihydropyridines.
Alginic acid was found to be an efficient, environmentally benign, easily recoverable and low-cost catalyst for clean synthesis of 1,4-dihydropiridine derivatives (DHPs).
Silica nanoparticles as a highly efficient catalyst for the one-pot synthesis of sterically congested 2-(dibenzylamino)-2-aryl acetamide derivatives from by phthaldehyde isomers, isocyanides and dibenzylamine
