The in situ-generated pyrrolin-3-ones serve as novel and versatile synthons, being employed intermediates for the efficient production of pyrrole-fused lactones with high yield excellent enantioselectivity. Herein, we introduce emerging rhodium oxidative N-heterocyclic carbene relay catalysis that enables a highly enantioselective cascade annulation between easily available 1,2,3-triazoles enals. In this proof-of-concept study, engage α,β-unsaturated acylazolium generated from enals via catalysis.
