Disclosed are compounds having the structure of Formula I, or a pharmaceutically acceptable salt of any thereof: wherein: "Z" and R1 are defined herein, which compounds are believed suitable for use in selectively antagonizing the A2a receptors, for example, those found in high density in the basal ganglia. Such compounds and pharmaceutical formulations are believed to be useful in treatment or management of neurodegenerative diseases, for example, Parkinson's disease, or movement disorders arising from use of certain medications used in the treatment or management of Parkinson's disease.

dozens of biologically active 2-substituted and 2,6-disubstituted piperidines, only a limited number of approaches exist for their synthesis. Herein is described two Mannich-type additions to nitrones, one using β-ketoacids under catalyst-free conditions and another using methyl ketones in the presence of chiral thioureas, which can generate a broad array of such 2-substituted materials, as well as other
