Nitrogen-containing π-excessive aromatic heterocycles, in particular, carbazoles,
indolocarbazoles, benzocarbazoles, and carbolines have been considered the fundamental …

The developments of theoretical studies on NHC‐catalyzed [n+ 2](n= 2, 3, 4) and other
cycloaddition/annulation reactions have been summarized in this review. The detailed …

First reported less than a decade ago, the α, β-unsaturated acyl azolium has emerged as a
central reactive intermediate for reaction discovery using N-heterocyclic carbene catalysis …

Chiral NHC-catalyzed kinetic resolution of N-aryl aminomaleimides allowing the synthesis of
C–N axially chiral N-aryl aminomaleimides via remote chirality control is presented. The …

Organocatalytic asymmetric [3+ 3] annulations of isatin-derived MBH carbonates and indolin-
2-imines were efficiently achieved. This appears to be the first enantioselective approach for …

In recent years, N-heterocyclic carbenes (NHCs) have established themselves as a
masterful and promising type of organocatalyst for the speedy construction of medicinally …

An NHC-catalyzed atroposelective synthesis of axially chiral α-carbolinones from α, β-
unsaturated iminoindole derivatives and α-chloroaldehydes was developed. The reaction …

The reactivity of 2-sulfonamidoindoles with acetoxy allenoates under phosphine catalysis
depends on the disposition of the acetoxy (OAc) group on the allenoate. In the temperature …

N-Heterocyclic carbene catalyzed enantioselective functionalization of 3-aminobenzofurans
at the C2-position was realized using 2-bromoenals as the coupling partner. The reaction …

Indole‐based heterocycles containing sulfur or nitrogen atoms are important frameworks
that occur widely in biological active natural products and drugs. Consequently, several …
