(Trifluoromethyl)-, nitro-, and other benzyl esters substituted with electron-withdrawing groups were specific for A3 receptors with nanomolar Ki values and selectivity as high as 37000-fold. A functionalized congener bearing an [(aminoethyl)amino]carbonyl group was also prepared as an intermediate in the synthesis of biologically active conjugates.

A facilesynthesis of Hantzsch 1,4-dihydropyridines with unsymmetrical 2,6- and 3,5-substituents in a one-pot two-step tandem reaction undersolvent-freeconditions, promoted by microwave irradiation, has been developed. No catalysts are used and the work-up is easy. This approach provides a convenient, efficient and practical synthesis of 1,4-dihydropyridines having non-identical substituents at the
