Organic synthesis using photoredox catalysis [PDF]
Beilstein Journal of Organic Chemistry, 2014 Natural photosynthesis is a remarkable chemical machinery that enables our life on earth and delivers a constant stream of oxygen and organic biomass. We should acknowledge this fact with humbleness, especially because we have not been able yet to mimic this process in a reliable way even after decades of intense research.

Functionalized Polyamine Synthesis with Photoredox Catalysis
Chemistry – A European Journal, 2023 Abstract Polyamines, such as putrescine and spermidine, are pivotal in various biological processes across living organisms. Despite their significance, structurally modified polyamines offer a less‐explored avenue for discovering bioactive compounds. The limitation is attributed to the synthetic difficulty of accessing functionalized
