vastly underutilized as coupling partners in transition metal catalysis. Herein, we describe a copper metallaphotoredox manifold for the open shell deoxygenative coupling of alcohols with N-nucleophiles to forge C(sp3)–N bonds, a linkage of high value in pharmaceutical agents that is challenging to access via conventional cross-coupling techniques. N-heterocycliccarbene (NHC)-mediated conversion of
Azanorbornylpurine derivatives were prepared by Mitsunobu reaction of appropriate hydroxyazanorbornane derivative with 6-chloropurine or construction of purine base at azanorbornylamines. The prepared target compounds were evaluated for antiviral activity and effect on neuronal and muscle nicotinic acetylcholine receptors. (C) 2011 Published by Elsevier Ltd.
