Intramolecular dehydrogenative cyclization of aliphatic amides was achieved on unactivated sp3 carbon atoms by a nickel-catalyzed C-H bond functionalization process with the assistance of a bidentate directing group. The reaction favors the C-H bonds of β-methyl groups over the γ-methyl or β-methylene groups. Additionally, a predominant preference for the β-methyl C-H bonds over the aromatic sp2 C-H bonds was observed. Moreover, this process also allows for the effective functionalization of benzylic secondary sp3 C-H bonds. β-Lactams from nickel catalysis: Intramolecular dehydrogenative cyclization of aliphatic amides was achieved on unactivated sp3 carbon atoms by a nickel-catalyzed C-H bond functionalization process with the assistance of a bidentate directing group (see scheme).
Potent and selective P2-P3 ketoamide inhibitors of cathepsin K with good pharmacokinetic properties via favorable P 1′, P1, and/or P3 substitutions

A series of ketoamides were synthesized and evaluated for inhibitory activity against cathepsin K. Exploration of the interactions between achiral P2 substituents and the cysteine protease based on molecular modeling suggestions resulted in potent cathepsin K inhibitors that demonstrated high selectivity versus cathepsins B, H, and L. Subsequent modifications of the P3, P1, and P1′ moieties afforded orally bioavailable inhibitors. A series of ketoamides were synthesized and evaluated for inhibitory activity against cathepsin K.

A systematic structure-activity relationship investigation of the lead compound 1 resulted the identification of several N-[(substituted alkyl)cycloalkanoyl]-4-[((2,6-dichlorophenyl)carbonyl)amino]-L-phenylalanine derivatives as potent VCAM/VLA-4 antagonists. The data are consistent with a model of these compounds in which these alkanoylphenylalanines reside in a compact gauche (-) bioactive conformation.
