Abstract

N-Substituted amino-2(5H)-oxazolones A are a novel class of insecticides acting as nicotinic acetylcholine receptor (nAChR) agonists and show potent activity against hemipteran insect species. Here we report the discovery and preparation of this class of chemistry. Our efforts in SAR elucidation, biological activity evaluation, as well as mode-of-action studies are also presented.

Keywords: Acetylcholine receptor; Insecticide; Neonicotinoid; Oxazolone.
