Synthesis of Stable Betaines Based on 1H-Pyrrole-2,3-diones and Pyridinium Ylides and Their Thermal Conversion to Cyclopropane-Fused Pyrroles [PDF]
MoleculesPyridinium ylides, along with related azaheterocyclic ylides, are widely used in synthetic organic chemistry. However, reactions that yield stable zwitterionic adducts from these ylides remain underexplored. In this work, we demonstrate that the reaction

Recent Developments in Azomethine Ylide-Initiated Double Cycloadditions [PDF]
MoleculesAzomethine ylides (AMYs) have a nitrogen–carbon double bond and an electron lone pair on the nitrogen atom. They are essential 1,3-dipoles for [3+2] cycloadditions in the synthesis of pyrrolidine-containing heterocycles.

Intramolecular Cycloaddition of Imines of Cysteine Derivatives
Molecules, 1998 Azomethine ylides were generated from Schiffs bases of S-allylcysteine methyl ester and their intramolecular 1,3-dipolar cycloadditions were studied. These reactions led to the synthesis of thieno[3,4-b]pyrrole derivatives in good yield.
