Practical and innate carbon-hydrogen functionalization of heterocycles.

ABSTRACT: Nitrogen-rich heterocyclic compounds have had a profound effect on human health because these chemical motifs are found in a large number of drugs used to combat a broad range of diseases and pathophysiological conditions. Advances in transition-metal-mediated cross-coupling have simplified the synthesis of such molecules; however, C-H functionalization of medicinally important heterocycles that does not rely on pre-functionalized starting materials is an underdeveloped area. Unfortunately, the innate properties of heterocycles that make them so desirable for biological applications--such as aqueous solubility and their ability to act as ligands--render them challenging substrates for direct chemical functionalization. Here we report that zinc sulphinate salts can be used to transfer alkyl
