, p. 1380 - 1385 (2019)
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-based approach to improved affinity and specificity f

Quinolin-2(1H)-ones are one of the important classes of compounds due to their prevalence in natural products and in pharmacologically useful compounds. Here we present an unconventional and hitherto unknown photocatalytic approach to their synthesis from easily available quinoline-N-oxides. This reagent free highly atom economical photocatalytic method, with low catalyst loading, high yield and no undesirable by-product, provides an efficient greener alternative to all conventional synthesis reported to date. The robustness of the methodology has been successfully demonstrated with easy scaling up to the gram scale.

A practical and scalable synthesis of halo quinolin-2(1H)-ones is presented. The heterocycles are easily accessed from inexpensive halo anilines in a two-step sequence. The anilines are acylated with methyl 3,3-dimethoxypropionate under basic conditions in quantitative yields. The crude amides undergo cyclization in sulfuric acid to the desired halo quinolin-2(1H)-ones in 28-93% yield (2 steps). The synthetic sequence was successfully applied on 800 g scale. Anilines with strong electron withdrawing or electron donating groups were poor substrates for this procedure. 6-Iodoquinolin-2(1H)-one and 6-bromo-8-iodoquinolin-2(1H)-one were further functionalized to obtain quinolines substituted with various functional groups.
