A grinding-induced catalyst- and solvent-free synthesis of highly functionalized 1,4-dihydropyridines via a domino multicomponent reaction
Atul Kumar,Siddharth Sharma +1 more
TL;DR: A grinding-induced catalyst and solvent-free domino multicomponent reaction for the synthesis of 1,4-dihydropyridines has been developed using aldehydes, amines, DEAD (diethyl acetylenedicarboxylate), and malononitrile/ethyl cyanoacetate as discussed by the authors.
