Copper(I)-catalyzed interrupted click/radical relay: A four-component modular synthesis of triazole sulfones

A new, four component copper(I)-catalyzed interrupted click/radical relay cascade has been developed. This unprecedented interrupted click reaction provides a rapid modular synthesis of triazole sulfones, important privileged heterocyclic pharmacophores which cannot be accessed by a traditional click reaction. Radical interception of cupratetriazole, the key reaction intermediate formed in situ , is an important feature of this process.(c) 2023 Published by Elsevier B.V. on behalf of Chinese Chemical Society and Institute of Materia Medica, Chinese Academy of Medical Sciences.
