A general synthesis of azetidines by copper-catalysed photoinduced anti-Baldwin radical cyclization of ynamides [PDF]
Nature Communications, 2022 The construction of four-membered rings via a 4-exo-dig cyclization was originally theorized to be unfavourable and only recently shown in sparse examples.

Radical Anions from Urea‐type Carbonyls: Radical Cyclizations and Cyclization Cascades [PDF]
Angewandte Chemie, 2018 AbstractRadical anions generated from urea carbonyls by reductive electron transfer are exploited in carbon–carbon bond formation. New radical cyclizations of urea radical anions deliver complex nitrogen heterocycles and, depending upon the proton source used in the reactions, a chemoselective switch between reaction pathways can deliver two ...
