Abstract

An efficient, one-pot multicomponent synthetic protocol toward substituted 1,4-dihydropyridines from aromatic amines, β-keto derivatives, and ethyl propiolate mediated by Mg(ClO4)2 is described. When ortho- or meta-substituted arylamines are used, two conformational isomers are generated. An NMR spectroscopic study of the energy barrier involved in the interconversion of the isomers is reported.
