Azirine-containing dipeptides and depsipeptides: synthesis, transformations and antibacterial activity.

Organic & biomolecular chemistry

Rostovskii NV, Koronatov AN, Sakharov PA, Agafonova AV, Novikov MS, Khlebnikov AF, Rogacheva EV, Kraeva LA.
PMID: 33170920
Org Biomol Chem. 2020 Dec 07;18(46):9448-9460. doi: 10.1039/d0ob02023k.

Azirine-containing dipeptides and depsipeptides with a wide range of substituents have been synthesized in high yields via the Passerini and Ugi multicomponent reactions (MCRs) using 2H-azirine-2-carboxylic acids as the acid component. The obtained MCR adducts have been transformed to...

Lewis acid-mediated synthesis of mono- and tris-indole adducts from chiral aziridines.

Organic & biomolecular chemistry

Macha L, Singh D, Rhee HJ, Ha HJ.

Org Biomol Chem. 2020 Dec 07;18(46):9473-9482. doi: 10.1039/d0ob01865a.

Lewis acid-mediated regio- and stereoselective nucleophilic addition of 2- or 3-substituted indoles to non-activated aziridine-2-carboxaldehydes in dioxane afforded 2-(indol-3-ylhydroxymethyl)aziridines whose ring opening with various nucleophiles rendered multi-substituted tryptamine derivatives. The reaction of the same aziridine-2-carboxaldehyde with three moles of...

Hypervalent-Iodine(III)-Mediated Tandem Oxidative Dearomatization/Aziridination of Phenolic Amines: Synthesis of Functionalized Unactivated Aziridines.

Chemistry (Weinheim an der Bergstrasse, Germany)

Cao YX, Silalai P, Liu CF, Yu KY, Bao X, Zhao XH, Saeeng R, Fan CA.
PMID: 33844345
Chemistry. 2021 Jun 10;27(33):8473-8478. doi: 10.1002/chem.202100762. Epub 2021 May 11.

A new hypervalent-iodine(III)-mediated tandem reaction involving oxidative dearomatization and in situ aziridination of phenolic amines is described, providing a mild and effective method for the assembly of structurally interesting and synthetically useful aziridines. Importantly, the densely functionalized aziridines resulting...

Copper-Catalyzed Ring-Opening Reactions of Alkyl Aziridines with B.

Molecules (Basel, Switzerland)

Favero L, Menichetti A, Boldrini C, Comparini LM, Di Bussolo V, Di Pietro S, Pineschi M.

The possibility to form new C-B bonds with aziridines using diboron derivatives continues to be a particularly challenging field in view of the direct preparation of functionalized β-aminoboronates, which are important compounds in drug discovery, being a bioisostere of...
