The chemistry of heterocyclic compounds has traditionally been and remains a bright area chemical science in Russia. This is due to the fact that many heterocycles find widest application. These are key structural fragments most drugs, plant protection agents. Many natural also derivatives heterocycles. At present, more than half hundreds millions known collective review devoted achievements Russian chemists this field over last 15–20 years. presents leading heterocyclists representing both RAS institutes university science. It worth noting wide scope review, terms geography author teams, covering whole our large country, diversity research areas. Practically all major types represented review. special attention focused on practical applications design new drugs biologically active compounds, high-energy molecules, materials for organic electronics photovoltaics, ligands coordination chemistry, other rapidly developing advances would not be possible without development fundamental transformations chemistry.<br> Bibliography — 2237 references.

Pseudo-multicomponent reactions

RSC Advances, Год журнала: 2023, Номер 13(24), С. 16091 - 16125

Опубликована: Янв. 1, 2023

Pseudo-MCRs are domino-type one-pot processes that involve combinations of at least three reactants (similarly to normal MCRs) but in which one them is stoichiometrically duplicated (or more) and hence takes part into two reaction steps more).

Domino Approach for the Synthesis of Pyridinium Salts and 1,2,3,8a-Tetrahydroimidazo[1,2-a]pyridines from 2-Imidazolines and Propiolic Acid Esters

The Journal of Organic Chemistry, Год журнала: 2023, Номер 88(16), С. 11603 - 11617

Опубликована: Июль 26, 2023

Adducts of 1-alkyl-2-imidazolines and two molecules alkyl propiolate, possessing an N-propargyl-β-enaminoester fragment, easily undergo a domino reaction to form pyridinium salts with β-(alkylammonio)ethyl group at the nitrogen atom in presence 2 equiv protic acid. Treatment above mixture base gives 1,2,3,8a-tetrahydroimidazo[1,2-a]pyridines. Reaction latter compounds acid chlorides affords β-(alkylamido)ethyl moiety atom.

Cu‐promoted Access to 1,4‐Diazine‐fused Isoindoles Through Concomitant Csp3‐N and Csp2‐N Bonds Formation Starting from Constrained N,O‐acetals

Advanced Synthesis & Catalysis, Год журнала: 2024, Номер 366(24), С. 5089 - 5099

Abstract Scarce dihydro‐1,4‐diazinoisoindole framework bearing two points of diversity was prepared through a cascade process based on concomitant C sp 3 − N and 2 bond formation. This approach consists an amidation in basic medium tosyl group by nucleophilic substitution followed Cu‐mediated Goldberg reaction the same operation. The required β‐bromoenamide obtained tosylation fused brominated N,O ‐acetals for first time acidic using submolar amounts PTSA. piperazines are useful building blocks as illustrated formation pentacyclic product via intramolecular interception enamide function.
