Diverse C-H functionalization strategies: modern solution for sustainable synthesis of complex molecules

Abstract:

C-H activation has been one of the most rapidly expanding fields of synthetic chemistry. Over the last decade, it has established itself as a prominent tool to build up molecular complexity in a more sustainable manner. Stereoselective C-H activation offers, in particular, a great opportunity to access high-value-added chiral molecules from the very simple precursors. Our group is thus particularly interested in the development of new methodologies for asymmetric C-H activation. Following this goal, we have designed a general and highly efficient synthesis of axially chiral biaryl compounds, via sulfoxide-directed C-H activation. Besides, the sulfoxide motif has also turned out to be a unique handle to design new chiral ligands for enantioselective C(sp3)-H activation.In addition C-N axially chiral molecules have been attracting growing interest, but an asymmetric synthesis of such scaffolds is still very rare. We have thus designed the first metal-catalyzed atroposelective N-arylation. Such unique asymmetric Ullmann coupling delivers the C-N axially chiral compounds, appealing skeletons for the pharmaceutical industry. Finally, truly sustainable, metal-free functionalizations of biologically relevant heterocyclic compounds, implying visible-light activation, will be discussed.
