Methyl Esters as Cross-Coupling Electrophiles: Direct Synthesis of Amide Bonds

Amide bond formation and transition metal-catalyzed cross-coupling are two of the most frequently used chemical reactions in organic synthesis. Recently, an overlap between these two reaction families was identified when Pd and Ni catalysts were demonstrated to cleave the strong C-O bond present in esters via oxidative addition. When simple methyl and ethyl esters are used, this transformation provides a powerful alternative to classical amide bond formations, which commonly feature stoichiometric activating agents. Thus far, few redox-active catalysts have been demonstrated to activate the C(acyl)-O bond of alkyl esters, which makes it difficult to perform informed screening when a challenging reaction needs optimization. We demonstrate that Ni catalysts bearing diverse NHC, phosphine, and nitrogen-containing ligands can all be used to activate methyl esters and enable their use in direct amide bond formation.

Coumarin versus Chromone Monoamine Oxidase B Inhibitors: Quo Vadis?

Because of the lack of significant disease-modifying drugs for neurodegenerative disorders, a pressing need for new chemical entities endowed with IMAO-B still exists. Within this framework, and for the first time, a study was performed to compare coumari

Novel 3-carboxamide-coumarins as potent and selective FXIIa inhibitors

Recently, FXIIa was highlighted as an original attractive target for the development of new anticoagulant drugs with low rates of therapy-related hemorrhages. In this work, we describe the development of a new series of 3-carboxamide-coumarins that are the first potent and selective nonpeptidic inhibitors of FXIIa.

Synthesis and pharmacological activity of 2-oxo-(2H) 1-benzopyran-3-carboxamide derivatives

Continuing our research on the synthesis and biological activity of heterocyclic compounds synthesized by carbon suboxide, we prepared and screened some 2-oxo-(2H) 1-benzopyran-3-carboxamide derivatives. The results of pharmacological assays are reported

Photolysis of Acyl Azides Leading to Acyl Nitrenes

Photolysis of acyl azides is shown to give acyl nitrenes in the triplet state and not in the single state.The acyl nitrenes have been trapped by hydrocarbons and aniline.
