A tunable cascade reaction of ureidomalonates and alkenyl azlactones was disclosed, which gave rise to the construction N-aroyl α-amino acid ester imide-functionalized hydantoins in moderate good yields with excellent diastereoselectivities. The pathway precisely manipulated by organocatalysis phase-transfer/sunlight relay catalysis, respectively, realize divergent synthesis. successful gram-scale preparation representative products exhibited application potential this protocol. Mechanistic studies indicated that exchange phase transfer ethoxy anion played a key role altering pathway, sunlight might accelerate oxidation process at late stage triggered phase-transfer catalysis.

Abstract Cascade radical cyclization constitutes an atom‐ and step‐economic route for rapid assembly of polycyclic molecular skeletons. Although array redox‐active metal catalysts has recently shown robust applications in enabling various catalytic cascade processes, the use free organic as catalyst, which is capable triggering strategically distinct cascades, rarely been developed. Here, we disclosed that benzimidazolium‐based N ‐heterocyclic carbene (NHC)‐boryl catalyzing reactions both intra‐ intermolecular pathways, assembling [5,5] fused bicyclic [6,6,6] tricyclic molecules, respectively. The start with chemo‐ regioselective addition boryl catalyst to a tethered alkene or alkyne moiety, followed by either intramolecular formal [3+2] [2+2+2] cycloaddition process construct bicyclo[3.3.0]octane tetrahydrophenanthridine skeletons, Eventually, β‐elimination occurs release completing cycle. High excellent diastereoselectivity achieved under substrate control.
