RESUMEN
The synthesis of two series of 4'-aza-carbocyclic nucleosides are described in which the 4'-substituent is either a reversed amide, relative to the carboxamide of NECA, or an N-bonded heterocycle. Using established purine substitution patterns, potent and selective examples of agonists of the human adenosine A(2A) receptor have been identified from both series. The propionamides 14-18 and the 4-hydroxymethylpyrazole 32 were determined to be the most potent and selective examples from the 4'-reversed amide and 4'-N-bonded heterocyclic series, respectively.
