5-Formyltriazoles as Valuable Starting Materials for Unsymmetrically Substituted Bi-1,2,3-Triazoles
Frontiers in Chemistry, 2020 Herein, we present the first synthetic methodologies toward non-symmetrical 5,5′-C, C-linked bi-1,2,3-triazoles starting from 5-formyl-1,2,3-triazole via two related pathways.

Phospha-munchnones: electronic structures and 1,3-dipolar cycloadditions
, 2010 The reaction of imines, acid chlorides, PR, and base generates a new class of 1,3-dipoles: phospha-Münchnones. These 1,3-dipoles can undergo cycloadditions with alkynes followed by loss of phosphine oxides to form pyrroles.

Push–Pull Ynamines and Push–Pull Ynamides: Synthesis, Structure, Reactivity, and Application
European Journal of Organic Chemistry, Volume 29, Issue 19, 22 May 2026.Push–pull ynamines and push–pull ynamides, which carry an EWG and an amino or amido group as EDG, are highly interesting classes of EDG‐EWG alkynes that have been intensively studied due to their exceptional reactivity. In this review, the synthesis, structure, reactivity, and application of push–pull ynamines, push–pull ynecarbamates, push–pull ...

1,2‐Diazetidines − Structure, Synthesis, and Functionalization
European Journal of Organic Chemistry, Volume 29, Issue 19, 22 May 2026.1,2‐Diazetidines are saturated four‐membered heterocycles featuring two adjacent nitrogen atoms. Despite recent advances in their synthesis and promising potential in medicinal chemistry, the chemistry of these cyclic hydrazines remains underexplored.

European Journal of Organic Chemistry, Volume 29, Issue 19, 22 May 2026.A cascade reaction under phase‐transfer conditions between 3‐nitro indoles and isocyanomethylene dibenzenes affords the construction of pyrrolo[3,4‐b]indole cores. Control experiments provide insight into moderate product yields and clarify why the reaction is not amenable to asymmetric induction. A cascade reaction enabling the construction of pyrrolo[
