A series of benzofuran and benzo[b]thiophen derivatives was synthesized via a transition-metal-free one-pot process at roomtemperature. This one-pot protocol enables the synthesis of compounds with high reaction efficiency, mild conditions, simple methods, and a wide-ranging substrate scope. Regioselective five-membered heterocycles were constructed in good-to-excellent yields.

The identification and hit-to-lead exploration of a novel, potent and selective series of histamine H(4) receptor inverse agonists is described. The initial hit, 3A (IC(50) 19 nM) was identified by means of a ligand-based virtual screening approach. Subsequent medicinal chemistry exploration yielded 18I which possessed increased potency (R-enantiomer IC(50) 1 nM) as well as enhanced microsomal stability. (C) 2010 Elsevier Ltd.
