Autor: Gleb D. Titov, Nikolai V. Rostovskii

Publikováno v: Molbank, Vol 2024, Iss 2, p M1799 (2024)

The previously unknown cyclopropane spiro-fused with isoxazol-5-one ((1RS,3SR)-1-(4-methylbenzyl)-7-phenyl-5-oxa-6-azaspiro[2.4]hept-6-en-4-one) was synthesized from benzylideneisoxazol-5-one in 34% yield via double methylene transfer from diazometha

Electrocyclizations of Conjugated Azapolyenes Produced in Reactions of Azaheterocycles with Metal Carbenes

Autor: Nikolai V. Rostovskii, Mikhail S. Novikov, Alexander F. Khlebnikov

Publikováno v: Organics, Vol 2, Iss 3, Pp 313-336 (2021)

Conjugated azapolyenes (azabuta-1,3-dienes, aza-/diaza-/oxaza-/oxadiazahexa-1,3,5-trienes) are highly reactive in electrocyclization reactions, which makes them convenient precursors for the synthesis of a wide range of four-, five-, and six-membered

Triethylamine-Promoted Oxidative Cyclodimerization of 2H-Azirine-2-carboxylates to Pyrimidine-4,6-dicarboxylates: Experimental and DFT Study

Autor: Timofei N. Zakharov, Pavel A. Sakharov, Mikhail S. Novikov, Alexander F. Khlebnikov, Nikolai V. Rostovskii

Publikováno v: Molecules, Vol 28, Iss 11, p 4315 (2023)

An unprecedented oxidative cyclodimerization reaction of 2H-azirine-2-carboxylates to pyrimidine-4,6-dicarboxylates under heating with triethylamine in air is described. In this reaction, one azirine molecule undergoes formal cleavage across the C-C

Selective and Reversible 1,3-Dipolar Cycloaddition of 2-(2-Oxoindoline-3-ylidene)acetates with Nitrones in the Synthesis of Functionalized Spiroisoxazolidines

Autor: Dmitriy D. Karcev, Mariia M. Efremova, Alexander P. Molchanov, Nikolai V. Rostovskii, Mariya A. Kryukova, Alexander S. Bunev, Dmitry A. Khochenkov

Publikováno v: International Journal of Molecular Sciences, Vol 23, Iss 20, p 12639 (2022)

The 1,3-dipolar cycloaddition of 2-(2-oxoindoline-3-ylidene)acetates with functionalized aldo- and ketonitrones proceeds with good selectivity to provide new highly functionalized 5-spiroisoxazolidines. A characteristic feature of these reactions is

Copper(II)-Catalyzed (3+2) Cycloaddition of 2H-Azirines to Six-Membered Cyclic Enols as a Route to Pyrrolo[3,2-c]quinolone, Chromeno[3,4-b]pyrrole, and Naphtho[1,8-ef]indole Scaffolds

Autor: Pavel A. Sakharov, Nikolai V. Rostovskii, Alexander F. Khlebnikov, Mikhail S. Novikov

Publikováno v: Molecules, Vol 27, Iss 17, p 5681 (2022)

A method for the [2+3] pyrroline annulation to the six-membered non-aromatic enols using 3-aryl-2H-azirines as annulation agents is developed in the current study. The reaction proceeds as a formal (3+2) cycloaddition via the N1-C2 azirine bond cleav
