Visible-Light Induced Trifluoromethylation of <i>N</i>-Arylcinnamamides for the Synthesis of CF<sub>3</sub>-Containing 3,4-Disubstituted Dihydroquinolinones and 1-Azaspiro[4.5]decanes
of N-arylcinnamamides with Togni’s reagent has been explored. This method allows for an efficient and practical synthesis of a variety of CF3-containing dihydroquinolin-2(1H)-ones and 1-azasporo[4.5]decanes bearing various functional groups under mild conditions.

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
