Rhodium(iii)-catalyzed diverse [4 + 1] annulation of arenes with 1,3-enynes via sp3/sp2 C–H activation and 1,4-rhodium migration

Nitrogen-rich heterocyclic compounds have a profound impact on human health. Despite the numerous synthetic methods, diversified, step-economic, and general synthesis of heterocycles remains limited. C–H bond functionalization catalyzed by rhodium(iii) cyclopentadienyls has proven to be a powerful s...
