An atom-efficient and transition metal-free approach to amides from the corresponding benzyl hydrocarbons through C–H and C–C bond cleavage has been developed. Mechanistic studies have shown that a DDQ-promoted cross-dehydrogenative coupling (CDC) reaction with subsequent oxidation and rearrangement are involved in this transformation.
A catalytic regio- and enantioselective haloazidation reaction with a chiral iron(II) complex catalyst under mild reaction conditions was reported. By this approach, the stereoselective α-halo-β-azido difunctionalization of both α,β-unsaturated amides and α,β-unsaturated esters was achieved. This method enabled the construction of a broad spectrum of valuable functionalized amides and esters, including

High-affinity, selective ligands are sought for a variety of biomolecules but are particularly difficult to generate in the protein–protein interaction space. Rhodium(II) conjugates provide a structure-basedapproach to improved affinity and specificity for targeting protein–protein interactions such as SH3 domains. In this study of small-molecule–rhodium conjugates, we report a potent ligand 4b (Kd of 27 nM)

Thienopyridine sulfonamide pyrrolidinones were found to be potent and selective inhibitors of the coagulation cascade enzyme factor Xa. SAR studies led to several compounds that were selected for further in vivo investigation. These novel aryl binding pocket moieties represent a structural modification to a series of fXa inhibitors. Several compounds proved to be efficacious i.v. antithrombotic agents
