BIGINELLI REACTION -- PHENYLETHYLAMINE -- ALUMINUM OXIDES
Аннотация: The asym. Biginelli reaction was investigated in the presence of N-​[(2S,​4R)​-​4-​hydroxyprolyl]​-​(S)​-​1-​phenylethylamine as chiral inducer and silicon, titanium or aluminum oxides (individual and mixed, bulk and nanosized) as heterogeneous catalysts. The synthesis of Et (4R)​-​6-​methyl-​2-​oxo-​4-​phenyl-​1,​2,​3,​4-​tetrahydropyrimidine-​5-​carboxylate from benzaldehyde, urea and Et acetoacetate has been described. It has been shown that all studied oxides improve chemo- and stereoselectivity of the Biginelli reaction.

HERBICIDES -- PYRENE DERIVATIVES
Аннотация: Pyrene-contg. water-sol. probes for the fluorescent detection of nitroarom. compds. (NACs), such as explosive components (2,4-DNT and 2,​4,​6-​TNT) and herbicides (2,4-​dinitrocresol, 2,4-DNOC)​, in aq. media are reported. In the probes, the introduction of surface-​active hydrophilic heads at the periphery of lipophilic (i.e., hydrophobic) pyrene tails resulted in the formation of highly fluorescent micelle-​like aggregates​/pre-​assocs. in aq. solns. at concns. of ≤10-5M. The enhanced fluorescence quenching of the herein reported architectures is achieved in the presence of ultra-​trace amts. of TNT or 2,4-DNT with values of Stern-​Volmer quenching const. close to 1 × 105M and a detection limit as low as 182 ppb. The most hydrophilic probes demonstrated higher response to 2,​4-​DNT over TNT. Filter paper test strips impregnated with 1 × 10-​5M solns. of the probes were able to detect TNT, 2,​4-​DNT, and other NACs at levels as low as 50 ppb in water.

PYRIMIDINE -- ANTIMYCOBACTERIAL ACTIVITY -- TUBERCULOSIS
Аннотация: Various 5-(fluoroaryl)-4-(hetero)aryl substituted pyrimidines have been synthesized based on the Suzuki cross-coupling and nucleophilic aromatic substitution of hydrogen (S-N(H)) reactions starting from commercially available 5-bromopyrimidine and their antitubercular activity against Mycobacterium tuberculosis H(37)Rv has been explored. The outcome of the study disclose that, some of the compounds have showed promising activity in micromolar concentration against Mycobacterium tuberculosis H(37)Rv, Mycobacterium avium, Mycobacterium terrae, and multidrug-resistant strains isolated from tuberculosis patients in Ural region (Russia). The data concerning the 'structure-activity' relationship for fluorinated compounds have been discussed

PYRIMIDINE SCAFFOLD -- PERIMIDINE SYSTEMS -- BORONIC ACIDS
Аннотация: A convenient synthetic route to novel 7-​substituted benzo[f]​thieno[3,​2-​h]​quinazoline and 8-​substituted benzo[g,​h]​dithieno[2,​3-​e:3',​2'-​j]​perimidine systems, bearing the fused pyrimidine ring, has been advanced. A com. available 5-​bromopyrimidine was used as the starting material to obtain various polycyclic systems through the sequence of nucleophilic arom. substitution of hydrogen (the SNH reaction)​, Suzuki cross-​coupling and oxidative photocyclization. Evidence for the structure of benzo[g,​h]​dithieno[2,​3-​e:3',​2'-​j]​perimidines has been obtained by X-​ray crystallog. anal. MO calcns. (DFT)​, as well as redox and optical measurements for all new compds. have been performed. The data show that the reported polycyclic systems have potential for use in org. electronic applications. The synthesis of the target compds. was achieved using 5-​bromo-​4-​(2-​thienyl)​pyrimidine and (phenyl)​boronic acids as starting materials.

FUSED THIOPHENE -- PYRROLE RINGS -- FISCHER INDOLIZATION REACTION
Аннотация: A convenient approach to ladder-type 6H-benzo[4',5']thieno[2',3':4,5]thieno[3,2-b]indoles, e.g., I (X-rays single crystal structure shown)​, bearing various substituents in both terminal benzene rings has been developed. The protocol suggested for prepg. these N,S-​heteroacenes is based on using easily available reagents, such as cinnamic acids and arylhydrazines, which can be involved in the Fischer indole synthesis, as the key step. A similar condensed system of 12H-​benzo[4'',​5'']​thieno[2'',3'':4',5']​thieno[2',3':4,5]​thieno[3,2-b]indole, bearing six rings, has also been obtained.

Аннотация: Synthetic routes to novel N-(purin-6-yl)- and N-(2-aminopurin-6-yl) conjugates with amino acids and glycine-containing dipeptides were developed. In vitro testing of 42 new and known compounds made it possible to reveal a series of N-(purin-6-yl)- and N-(2-aminopurin-6-yl) conjugates exhibiting significant antimycobacterial activity against Mycobacterium tuberculosis H37Rv, Mycobacterium avium, Mycobacterium terrae, and multidrug-resistant M. tuberculosis strain isolated from tuberculosis patients in the Ural region (Russia). N-(2-Aminopurin-6-yl)- and N-(purin-6-yl)-glycyl-(S)-glutamic acids were the most active compounds. (C) 2016 Elsevier Ltd. All rights reserved
