Abstract

We aim the power of C-H bond functionalization at a problem of major practical consequence-namely, scalable access to drug metabolites and their analogs. In this context, we pursue the development of simple C-H oxidation methods that tolerate a wide range of functional groups and structural features found in pharmaceuticals ('chemotransformations'). In this Letter, we focus on N,. N-dimethylamines as they are frequently found in pharmaceuticals and undergo CYP-mediated N-demethylation reactions in vivo. The direct access to these in vivo metabolites, from the parent drugs, has remained a significant synthetic challenge for which a broad solution had not previously been found. We here show that a simple copper-oxygen catalytic system provides a scalable route to complex N-demethylated drug metabolites.
