Methylene-selective C-H functionalization is a significant hurdle that remains to be addressed in the field of Pd(II) catalysis. We report a Pd(II)-catalyzed synthesis of benzocyclobutenes by methylene-selective C(sp3)-H arylation of ketones. The reaction utilizes glycine as a transient directing group and a 2-pyridone ligand, which may govern the methylene selectivity by making intimate molecular associations with the substrate during concerted metalation-deprotonation. This reaction is shown to be highly selective for intramolecular methylene C(sp3)-H arylation, thus enabling sequential C(sp3)-H functionalization.

A palladium-catalyzed enantioselective coupling of 2,5-cyclohexadienyl-substituted aryl iodides and carbon or heteroatom nucleophiles is described. The reaction proceeded via a tandem asymmetric Heck insertion and Tsuji-Trost allylation, enabling the rapi

The development of the structure-activity studies leading to the discovery of anacetrapib is described. These studies focused on varying the substitution of the oxazolidinone ring of the 5-aryloxazolidinone system. Specifically, it was found that substitution of the 4-position with a methyl group with the cis-stereochemistry relative to the 5-aryl group afforded compounds with increased cholesteryl ester transfer protein (CETP) inhibition potency and a robust in vivo effect on increasing HDL-C levels in transgenic mice expressing cynomolgus monkey CETP.
