In this review, the advances made over the last 6 years in [4+ 1]-annulation reactions
involving sulfonium, sulfoxonium and ammonium ylides, as well as diazo compounds and …

Indoline is an important structural motif present in several biologically active compounds
from both natural and synthetic origins. The occurrence of this heterocyclic unity in these …

Presented herein is a condition-controlled selective synthesis of pyrazolonyl
spirodihydroquinolines or pyrazolonyl spiroindolines through formal [5+ 1] or [4+ 1] …

In this paper, an efficient synthesis of N-arylindoles through the cascade reaction of 2-
alkenylanilines with diazonaphthalen-2 (1 H)-ones is presented. Mechanistically, this …

Protodepalladation is the redox-neutral conversion of a C–Pd (II) bond into a C–H bond via
reaction with a Brønsted acid. It is the microscopic reverse of Pd (II)-mediated C–H cleavage …

We report a new method for the synthesis of indolines from o‐aminobenzylidine N‐
tosylhydrazones proceeding through a cobalt (III)–carbene radical intermediate. This …

Compared with the reported intramolecular electro-oxidative cyclization of alkenyl amines or
vinyl anilines for the preparation of pyrrolidines or indolines, the intermolecular version is …

Cyclopropenes are highly strained three-membered carbocycles, which offer unique
reactivity in organic synthesis. Herein, Cp* CoIII-catalyzed ring-opening isomerization of …

An efficient rhodium catalyzed [4+ 1]-annulation of o-acylanilines with 3-diazoindoline-2-
imines has been successfully accomplished for the synthesis of spiroindolines in good to …

An efficient rhodium catalyzed Sommelet–Hauser type rearrangement of sulfur ylides
derived from α-thioesters and N-sulfonyl-1, 2, 3-triazoles has been successfully …
