These compounds are synthesized from b-aryl pyrrolidines, providing products with the 2-arylethyl amine moiety, a structural feature often encountered in compounds active in the central nervous system. The b-aryl pyrrolidines are synthesized through a three-step methodology that includes a Knoevenagel condensation reaction, a 1,3-dipolar cycloaddition reaction, and a nitrile reduction. %K Knoevenagel condensation %K 1 %K 3-dipolar cycloaddition %K azomethine ylide %K parallel synthesis %K spiro dihydrouracils %U http://www.mdpi.com/1420-3049/15/4/2269
