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).

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.
