This review covers recent advances in decarboxylative photocatalysis applicable to the medicinal chemist. The review is not intended to be exhaustive, but instead is focussed on transformations that could be useful in the synthesis of drug-like compounds in order to highlight the utility of this methodology in the development of new pharmaceutical candidates.1 Introduction2 C–C Bond Formation3 C–N and C–O Bond Formation4 Fluorination and Trifluoromethylation5 Hydrodecarboxylation6 Protein Functionalisation7 Conclusion

As part of a drug discovery program, 4-pyrazin-2-yl-1H-pyrrole-2-carboxamides were accessed along with a number of bicyclic analogues. Routes to these compounds were largely absent from the scientific literature. The synthesis of a 4-(pyrazin-2-yl)-1H-pyrrole-2-carboxamide and several fused bicyclic analogues all using standard procedures (SNAr, borylation, C–C cross couplings, hydrolysis, amide bond formation, cyclisation, halogenation, and alkylation) from readily available starting materials is reported. The synthetic sequences range from 4–12 steps per final compound, with yields of isolated intermediates ranging from 20 to ∼100%.
