copper‐catalyzed cross‐coupling of 1,2‐dihaloalkenes and amides leads to cyclic β‐haloenamides, which can participate in a second cross‐coupling reaction to efficiently synthesize highly functionalized cyclic enamides. The selectivity of the intramolecular coupling between exo‐ and endocyclic regioisomers is a crucial synthetic factor and can be influenced by the structure of the substrate and the reaction conditions

novel, potent and selective oxytocin antagonists are reported. Combinatorial libraries designed to find novel replacements of fragments of oxytocin antagonist L-371,257, identified pyrimidine, thiazole, indole and benzofuran as potential alternatives to the benzoic acid moiety of L-371,257. Additional investigations identified indole and benzofuran derivatives with potent oxytocin antagonist activity

A series of hinge-binder tethered 1,2,3-triazolylsalicylamide derivatives were designed, synthesized, and evaluated for the Aurora kinase inhibitory activities. The novel hinge-binder tethered 1,2,3-triazolylsalicylamide scaffold was effectively assembled by Cu(I)-catalyzed azide-alkyne 1,3-dipolar cycloaddition (CuAAC). A variety of alkynes with hinge binders were used to search proper structures-binding relationship to the hinge region. The synthesized 1,2,3-triazolylsalicylamide derivatives showed significant Aurora kinase inhibitory activity. In particular, 8a inhibited Aurora A kinase with an IC50 value of 0.284 mu M, whereas 8m inhibited Aurora B kinase with an IC50 value of 0.364 mu M. (C) 2016 Elsevier Ltd. All rights reserved.
