3-Aryl-2H-azirines as annulation reagents in the Ni(II)-catalyzed synthesis of 1H-benzo[4,5]thieno[3,2-b]pyrroles [PDF]

open access: yesBeilstein Journal of Organic Chemistry
A high-yielding method for the synthesis of 3-arylbenzo[4,5]thieno[3,2-b]pyrroles has been developed via pyrrole ring annulation to the aromatic benzo[b]thiophene system, using 3-arylazirines as a N‒C=C synthon.

Enantiomerically Enriched Aziridine-2-carboxylates via Copper-Catalyzed Reductive Kinetic Resolution of 2H-Azirines [PDF]

open access: yesAngewandte Chemie, Volume 137, Issue 26, June 24, 2025.
We present the first reductive kinetic resolution of racemic 2H-azirines to prepare optically enriched N-H aziridine-2-carboxylates, which are bench stable and easily diversifiable building blocks, concomitantly with the corresponding enantiomerically ...

2H-Azirines as electrophiles [PDF]

open access: yes, 2011
2H-Azirines have shown an unusual potential to synthesise aziridines and other types of compounds. Many functionalized aziridines can be produced by addition of O-, S-,N-, C-nucleophiles and hydride to 2H-azirines. This review is designed to give an overview of the reactivity of 2H-azirines as electrophiles along the years and their usefulness in the ...

Cobalt catalyst with exclusive metal-centered chirality for asymmetric photocatalysis [PDF]

open access: yesNature Communications
For decades, progress in chiral transition metal catalysis has been closely linked to the design of tailor-made chiral ligands. Recently, an alternative to this conventional paradigm has emerged in which the overall chirality of the catalysts arises ...
