fLUORINATED QUINOLINES -- SYNTHETIC METHODS -- CYCLOADDITION REACTIONS
Аннотация: The data on the chemistry of fluorinated quinolines available in the literature of the last 10–15 years are presented. A variety of synthetic methods exploiting cyclization and cycloaddition reactions, displacements of halogen atoms or the diaza group, as well as direct fluorinations have been considered. Novel approaches to functionalization of polyfluorinated quinolines, including nucleophilic displacement of fluorine atoms, cross-coupling reactions, and synthesis on the basis of organometallic compounds are discussed. Selected representative examples of fluoroquinolines exhibiting a remarkable biological activity or those quinolines which have already found their applications in medicine will also be discussed in the text.

Аннотация: The data on 6-fluorо-1,4-dihydroquinolin-4-oxo-3-carboxylic acids and their structural analogues accumulated in the literature for the last 10–15 years are reviewed. Synthetic approaches to the quinolone system, as well as all kind of structural modifications by incorporating substituents into 1–8 positions or by means of annelation have been discussed. The “structure-activity” relationships for antibacterial fluoroquinolones, as well as the data on other types of biological activity for the family of bi- and polycyclic fluoroquinolones are presented.

Аннотация: Scieces of data on the synthesis and antitumour activity of 4-aminoquinazolines are summarized and analyzed. Key methods for the synthesis of these compounds are considered, primarily cyclocondensation of carboxylic acid derivatives, as well as the oxidation of quinazolines and the cyclization of disubstituted thioureas. Improvements of synthetic schemes for erlotinib, gefitinib and lapatinib, which are the best-known pharmaceuticals based on compounds of the title class, are also considered. Synthetic strategies and biological activities for new 4-aminoquinazoline derivatives that are EGFR-tyrosine kinase inhibitors, multiactive compounds, and labelled compounds for use as positron emission tomography (PET) imaging agents are discussed.

CHEMOENZYMATIC SYNTHESIS -- BENZIMIDAZOLES -- HERPES SIMPLEX VIRUS TYPE 1
Аннотация: 1-(2′-Deoxy-2′-fluoro-β-d-arabinofuranosyl)benzimidazoles containing 4,6-difluoro-, 4,5,6-trifluoro-, 5-fluoro-6-methoxy-, and 5-methoxy-4,6-difluorobenzimidazole fragments were synthesized by using purine nucleoside phosphorylase-catalyzed chemoenzymatic approach. As expected, enzymatic synthesis of nucleosides proceeds in lower yields of target compounds in comparison with the synthesis of ribo- and 2′-deoxyribobenzimidazoles (40–55% vs 60–90%). The compounds obtained were tested against the herpes simplex virus type 1, by using the Vero E6 cells. 5-Methoxy-4,6-difluoro-1-β-d-(2′-deoxy-2′-fluoroarabinofuranosyl)benzimidazole did not show any antiviral activity, when used in nontoxic concentration. All other nucleosides proved to exhibit a selective antiherpes activity. In contrast, it was shown that benzimidazole-β-d-arabinofuranosides of both di- and trisubstituted derivatives, having substituents in positions 4–6 of the benzene ring, as well as unsubstituted compounds, cannot be synthesized by enzymatic transglycosylation. 1-(β-d-Arabinofuranosyl)benzimidazole was obtained through glycosylation of N-trimethylsilylbenzimidazole with 1-chloro-2,3,5-O-methoxymethyl-d-arabinose. The behavior of this compound, as inhibitor of purine nucleoside phosphorylase (PNP) E. сoli, was investigated. 1-(β-d-Arabinofuranosyl)benzimidazole was found to belong to a mixed type of inhibitors of PNP. This fact explains why all attempts to perform enzymatic arabinosylation of 4,6-di-, 5,6-di-, and 4,5,6-trisubstituted benzimidazoles failed

ONE-POT SYNTHESIS -- DIELS-ALDER REACTIONS -- ELECTRON-DEFICIENT OLEFINS
Аннотация: Particular success has been achieved in the synthesis of new products and in processes since the twelve principles of "green chemistry" were formulated in the 1990s. These products and processes are more compatible with human health, society, and the environment. In this review, a collection of research reports have been documented from the viewpoint of green chemistry. The main theme of this review is neat reactions, which are solvent and catalyst-free reactions. Neat reactions in the absence of any solvent or catalyst with concise summaries of microwave, ball milling, and neat reactions have been described.

Basic research data were generalized on the synthesis and study of antiviral activity and the establishment of the metabolism and mechanism of azoloazine series compounds-azaanalogs of adenine and guanine, as well as their nucleosides, which led to the creation of a new family of antiviral substances. One of them, triazavirin, has become a regular therapeutic fixture as an antiflu preparation. The results of synthetic and biological studies on substituted pyrimidines, nucleosides of the benzimidazole and purine series, and other biologically active azaheterocycles are also discussed.

Аннотация: The synthesis of a series of push-pull aryl and arylethynyl 2-(thiophen-2-yl) quinazoline derivatives is presented. The photophysical properties of the newly generated compounds are also described. Functionalization of the (2-thienyl) quinazoline fluorophore at the 5'-position with aryl and arylethynyl moieties was performed using bromination and subsequent palladium-catalyzed cross-coupling reactions. Optical studies revealed that 4-(diethylamino) phenyl and 4-(diphen-ylamino) phenyl derivatives emit green light upon irradiation, whereas their 4-(9H-carbazol-9-yl) phenyl, methoxyphenyl, thienyl and arylethynyl counterparts are characterized by blue light emission capabilities. The effect of protonation has also been studied, and the ability of some of these molecules to function as colorimetric and luminescent pH sensors has been demonstrated with significant color changes and luminescence switching upon the introduction of acid.

Аннотация: A series of new 5,11-dihydroindolo[3,2-b]carbazole derivatives, containing functional thiophene, 2,2′-bithiophene or 2,2′:5′,2″-terthiophene moieties at both C-2 and C-8 positions of their fused scaffolds, have been obtained from 2,8-diacetyl-substituted 5,11-dihydroindolo[3,2-b]carbazole compounds through the effective strategy, which is based on the sequence of two reactions, namely the Vilsmeier–Haack formylation and the Fiesselmann thiophene synthesis. The starting acetyl substituted materials have been transformed into the corresponding 3-chlorocrylaldehyde-containing compounds by treatment with POCl3-DMF complex, followed by the reaction with alkyl thioglycolates or α-mercaptoacetone in the presence of triethylamine to afford 2-carboalkoxythiophene- or 2-acetylthiophene-linked derivatives. 2-Acetylthiophene derivatives have further been involved into the same sequence of reactions to obtain 2,2′-bithiophene-, and 2,2′:5′,2″-terthiophene-linked 5,11-dihydroindolo[3,2-b]carbazole compounds.
