1,2‐Diazetidines − Structure, Synthesis, and Functionalization
European Journal of Organic Chemistry, EarlyView.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, EarlyView.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[

Ruthenium-catalyzed azide alkyne cycloaddition reaction: scope, mechanism and applications [PDF]
, 2016 The ruthenium-catalyzed azide alkyne cycloaddition (RuAAC) affords 1,5-disubstituted 1,2,3-triazoles in one step and complements the more established copper-catalyzed reaction providing the 1,4-isomer.

Structure and Spectroscopy of Criegee Intermediates in Gas‐ and Aqueous Environments
Helvetica Chimica Acta, EarlyView.ABSTRACT The dynamics and spectroscopy of the small (H2COO) and large (CH3CHOO) Criegee intermediates (CIs) in the gas phase, inside/on water droplets, on amorphous solid water (ASW) and in bulk water are investigated using validated energy functions.

Angewandte Chemie, Volume 138, Issue 16, 13 April 2026.It may seem counterintuitive to first target a ruthenium alkylidyne when Grubbs‐type ruthenium carbene complexes are the actual goal. In the end, however, this tactic pays valuable dividends in terms of practicality, atom economy, flexibility as well as safety: the new route provides ready access to a large assortment of catalysts for alkene metathesis

Synthesis of enantiomeric polyhydroxyalkylpyrrolidines from 1,3-dipolar cycloadducts. Evaluation as inhibitors of a β-galactofuranosidase [PDF]
, 2016 Enantiomeric 2,3,4-tris(hydroxyalkyl)-5-phenylpyrrolidines have been synthesized from the major cycloadducts obtained by the 1,3-dipolar cycloaddition of sugar enones with azomethine ylides derived from natural amino acids.
