Palladium-catalyzed C(sp3)-H arylation of aliphatic carboxylic acids, amides and ketones with BNA-encoded aryl iodides in water is disclosed, Furthermore, sequential C-H arylation chemistry enabled the on-DNA synthesis of structurally-diverse scaffolds containing enriched C(sp3) character, chiral centers, cyclopropane, cyclobutane, and heterocycles. That new chemistry permits preparation of a DNA- encoded library (BEL) technology that can dramatically expedite hit identification in drug discovery owing to its ability to perform protein affinity selection with millions or billions of molecules in a single experiment. The sequential functionalization of multiple C-H bonds provides an unique avenue for creating diversity and complexity from simple starting materials. The use of water as solvent, the presence of DMA, and the extremely low concentration of DMA-encoded coupling partners (0.001 M) have previously hampered the development DMA-encoded C(sp3)-H activation reactions, but many of those hurdles have now been overcome.
