Although the demand for privileged (hetero) cyclic molecules continues to grow steadily in
organic synthesis, drug discovery, agrochemical chemistry, materials science, etc., the …

We report herein that a highly regioselective silicon–carbon bond-forming silylation of
unsymmetric gem-difluorocyclopropenes based on Si–C or Si–B bond cleavage of …

A highly efficient chiral phosphoric acid-catalyzed enantioselective Friedel–Crafts addition of
indolizine to cyclic N-sulfonyl imine has been established. The newly developed protocol …

A transition metal-and oxidant-free C–C/C–N annulation of azomethine imines with vinylene
carbonate as dual synthons under simple reaction conditions is described herein …

An organocatalytic highly diastero-and enantioselective Friedel–Crafts conjugate addition of
indolizines to prochiral cyclopentenediones has been successfully developed. This …

Dearomatization reactions provide a rapid approach to construct complicated molecules that
are difficult to synthesize by traditional methods from simple aromatic compounds. Herein …

The reaction of cyclopropenones with pyridines, having an attached integer-charged
electron-withdrawing group (pyridinium, imidazolium, and phosphonium) was discovered to …

An enantioselective Friedel–Crafts reaction of cyclic α-diaryl N-acyl imines with indolizines
catalyzed by a chiral spirocyclic phosphoric acid has been developed. The asymmetric …

An aerobic multicomponent reaction between monoalkyl-3, 3-difluorocyclopropenes,
pyridines, and arylthiols has been discovered to afford 3-arylsulfanyl-1-hydroxyindolizines …

The first example of the synthesis of 3-thioxo-3 H-indolizinium-1-olates, which further
expands a limited class of pseudocross-conjugated heterocyclic mesomeric betaines …
