Synthesis of new triazole-based trifluoromethyl scaffolds

Beilstein Journal of Organic Chemistry, 2008
Trifluoromethyl propargylamines react with various azide derivatives to afford 1,4-disubstituted 1,2,3-triazoles through a Huisgen 1,3-dipolar cycloaddition. The reaction is catalyzed by a Cu(I) species in acetonitrile, and the corresponding products are

Retro‐Hetero‐Michael Addition Strategies in Organic Synthesis

European Journal of Organic Chemistry, Volume 29, Issue 32, 24 August 2026.
In this review, synthetic approaches to carbo‐ and heterocyclic compounds, including natural products, published in the last 15 years (2011–2025) which have either relied upon or included a retro‐hetero‐Michael addition step at any stage are discussed.

Isotelluroureas for Asymmetric C1 Ammonium Enolate Reactions

European Journal of Organic Chemistry, Volume 29, Issue 31, 19 August 2026.
Chiral isotelluroureas are powerful catalysts for a variety of C─C bond forming C1 ammonium enolate transformations. Isotelluroureas (ITeUs) have recently been introduced as a novel class of highly nucleophilic Lewis base catalysts. Herein, we systematically screened them for their potential to facilitate C1 ammonium enolate transformations and ...

Inverting the Regioselectivity of 1,3-Dipolar Cycloaddition Reaction Between Nitrones and Enal Derivatives

Reactions
The 1,3-dipolar cycloaddition of nitrones with hydrazones affords 5-iminoisoxazolidines as the major products, in contrast to the reaction with enals, which exclusively afford 4-acylisoxazolidines.
