Efficient Synthesis of an Adenosine A2a Agonist: Glycosylation of 2-Haloadenines and an N2-Alkyl-6-chloroguanine

A convergent synthesis of adenosine A2a agonist 1 in the form of its maleate salt 2 was achieved. The key step in this approach was the highly selective 9β-glycosylation reaction between 2-haloadenines or an N 2-alkyl-6-chloroguanine and a D-ri
