Design, synthesis, and structure–activity relationship of novel CCR2 antagonists
摘要:
A series of novel 1-aminocyclopentyl-3-carboxyamides incorporating substituted tetrahydropyran moieties have been synthesized and subsequently evaluated for their antagonistic activity against the human CCR2 receptor. Among them analog 59 was found to posses potent antagonistic activity. (C) 2009 Published by Elsevier Ltd.

Two in two: Dioxygenation of alkenylboronicacids has been achieved with N‐hydroxyphthalimide. The two‐step process involves etherification of an alkenylboronicacid with N‐hydroxyphthalimide followed by a [3,3] rearrangement. The dioxygenated product can then be hydrolyzed to form either the corresponding α‐hydroxy ketone or the α‐benzoyloxy ketone.
The present invention relates to novel and selective antagonists for CCR2 (CC chemokine receptor 2) and their use for providing medicaments for treating conditions and diseases, especially pulmonary diseases like asthma and COPD as well as pain.

Catalytic and enantioselective approaches to transannular reactions are very limited and mostly are based on chiral Lewis acid catalyzed pericyclic reactions. In this report, we present an efficient and straightforward methodology to access bicyclic carbo- and heterocyclic scaffolds combining different ring sizes through transannular Morita-Baylis-Hillman reaction catalyzed by a chiral enantiopure
