bridged macrocyclic 1,4-dihydropyridines (7) have been synthesized by starting from valine, alanine, phenylglycine, phenylalanine, and proline. Various bridges of different compositions, lengths, and shapes have been incorporated. All these bridged compounds in a nonprotic solvent like CH3CN in the presence of a stoichiometric amount of Mg(ClO4)2·1.5H2O reduce activatedcarbonylcompounds to the corresponding
