Axially chiral aldehydes have received increasing attention in enantioselective catalysis.
However, only very few catalytic methods have been developed to construct structurally …

Abstract α‐Haloenals, especially, α‐bromoenals considered as one of the important building
blocks in organic synthesis. They can participate in various (3+ 2)‐,(3+ 3)‐,(3+ 4)‐, and (2+ …

The enantioselective synthesis of functionalized pyrazoloquinolin-3-ones via N-heterocyclic
carbene-catalyzed cascade reaction of α-bromoenals with 2-aminoaryl N-tosyl hydrazones …

An expeditious protocol for the assembly of chiral 4, 5-dihydropyridazin-3 (2 H)-ones from α-
chloro hydrazones and α-chloro aliphatic aldehydes via N-heterocyclic carbene (NHC) …

An unprecedented organocatalytic asymmetric construction of novel six-membered
carbocycle fused uracils has been demonstrated by the reaction of the remotely enolizable 6 …

Herein, we report an intriguing cascade strategy for synthesizing optically active fused
pyrazolidines featuring three contiguous stereogenic centers. The formyl-tethered enones …

Aminoindanol‐derived N‐heterocyclic carbene catalysts have been widely used to achieve
highly enantioselective reactions. Recently, substitution at the indane moiety of the catalysts …

Abstract An uncommon aza-Diels-Alder reaction of electron-deficient azoalkenes and
electron-deficient 3-phenacylideneoxindoles was successfully developed for convenient …

Selective oxidative C–O coupling of hydrazones with diacetyliminoxyl is demonstrated, in
which diacetyliminoxyl plays a dual role. It is an oxidant (hydrogen atom acceptor) and an O …

The reactivity of N‐Heterocyclic carbene (NHC)‐bound alkynyl acyl azoliums is
underexplored in chemistry. We herein reported an NHC‐catalyzed [3+ 3] annulation of …
