Open-Air Alkylation Reactions in Photoredox-Catalyzed DNA-Encoded Library Synthesis
Published on 2019-02-12T15:12:02Z (GMT) by
DNA-encoded library (DEL) technology is a powerful tool commonly used by the pharmaceutical industry for the identification of compounds with affinity to biomolecular targets. Success in this endeavor lies in sampling diverse chemical libraries. However, current DELs tend to be deficient in C(sp<sup>3</sup>) carbon counts. We report unique solutions to the challenge of increasing both the chemical diversity of these libraries and their C(sp<sup>3</sup>) carbon counts by merging Ni/photoredox dual catalytic C(sp<sup>2</sup>)–C(sp<sup>3</sup>) cross-coupling as well as photoredox-catalyzed radical/polar crossover alkylation protocols with DELs. The successful integration of multiple classes of radical sources enables the rapid incorporation of a diverse set of alkyl fragments.
