Optimized substituent patterns in 4-arul-puridine glucagon receptor antagonists were merged to produce highly potent derivatives containing both a 3-[(1R)-hydroxyethyl] and a 2'-hydroxy group. Due to restricted rotation of the phenyl-pyridine bond, these analogues exist as four isomers. A diastereoselective methylcopper reaction as developed to facilitate the synthesis, and single isomers ere isolated with activities in the range IC50 = 10 25 nM. (C) 2002 Elsevier Science Ltd.
