2-Arylbenzoxazoles as CETP inhibitors: Substitution and modification of the α-alkoxyamide moiety
摘要:
The development of a series of 2-arylbenzoxazole alpha-alkoxyamide and beta-alkoxyamine inhibitors of cholesteryl ester transfer protein (CETP) is described. Highly fluorinated alpha-alkoxyamides proved to be potent inhibitors of CETP in vitro, and the highly fluorinated 2-arylbenzoxazole beta-alkoxyamine 4 showed a desirable combination of in vitro potency (IC(50) = 151 nM) and oral bioavailability in the mouse.

Palladium-Catalyzed Direct Arylations, Alkenylations, and Benzylations through C−H Bond Cleavages with Sulfamates or Phosphates as Electrophiles
A catalytic system comprised of Pd(OAc)2 and bidentate ligand dppe enabled first direct arylations with moisture-stable aryl sulfamates as electrophiles, and proved applicable to unprecedented C−H bond functionalizations with easily accessible alkenyl phosphates as well as benzyl phosphates.
