An unprecedented reaction between quinolineN‐oxides with O‐benzoylhydroxylamines was developed by using CuCl as catalyst, generating deoxygenative products of 2‐aminoquinolines in good yields. 1,2‐Dichloroethane (DCE) as solvent also served as reducing agent to cleave the N–O bond with no additional reductant needed in the reaction.
significant decrease of catalytic reactivity. We herein disclose a nickel-catalyzed and a sacrificial N-oxide group directed oxidative coupling of (iso)quinolyl C–H bonds and alicyclic amines, which furnishes bioimportant amino(iso)quinolines efficiently and selectively in a single step. Noteworthy, this protocol avoids the use of aggressive reactants and very strongbases usually required when aminating

SCH 58261 is a reported adenosine A(2A) receptor antagonist, which is active in rat in vivo models of Parkinson's Disease upon ip administration. However, it has poor selectivity versus the A(1) receptor and does not demonstrate oral activity. We report the design and synthesis of biaryl and heteroaryl analogs of SCH 58261 which improve the A(2A) receptor binding selectivity as well as the pharmacokinetic properties of SCH 58261. In particular, the quinoline 25 has excellent A(2A) receptor in vitro binding affinity and selectivity, sustained rat plasma levels upon oral dosing, and is active orally in a rat behavioral assay.
