Model amino acidester conjugates bearing heterocycles with a thiocarbonyl group (thiocoumarins and thioquinolones) were prepared by a thionation reaction of the corresponding carbonyl precursors, with the aim of obtaining conjugates with higher photosensitivity at longer wavelengths. Photolysis studies were carried out under irradiation at different wavelengths in a photochemical reactor (250, 300

A mild method for the synthesis of 2-quinolinones via hydroarylation of N-aryl alkynamides is reported. While traditional methods have relied on the use of strong Brønsted or Lewis acids, this report describes the development of mild reaction conditions that yield 2-quinolinones in good to excellent yield using a commercially available gold catalyst.

An atom-efficient silver-catalysed double carboxylative strategy for the one-step synthesis of quinolin-2-ones via an addition–cyclisation–elimination cascade sequence of oxamic acids to acrylic acids, mediated either thermally or photochemically, is reported. The reaction was applicable to the synthesis of a broad range of quinolin-2-ones and featured a double-disconnection approach that constructed
