The development of versatile and sustainable catalytic strategies for amide bond formation is a major objective for the pharmaceutical sector and the wider chemical industry. Herein, we report a biocatalytic approach to amidesynthesis which exploits the diversity of Nature's amide bond forming enzymes, N-acyltransferases (NATs) and CoA ligases (CLs). By selecting combinations of NATs and CLs with
Efficient Synthesis of New <i>N</i>-Benzyl- or <i>N</i>-(2-Furylmethyl)cinnamamides Promoted by the ‘Green’ Catalyst Boric Acid, and Their Spectral Analysis
New N-benzyl- or N-(2-furylmethyl)cinnamamides were prepared in good to excellent yields by amidation reactions between cinnamic acid and benzylamines or (2-furylmethyl)amine in the presence of 5 mol% boric acid. All the cinnamamides were characterized by IR and 1H and 13C NMR spectroscopy.
