    Tandem AN—AN reactions in the synthesis of 1H-pyrrolo[3,2-e]-1,2,4-triazines and products of their oxidative transformations [Electronic resource] / V. N. Charushin, N. N. Mochul`skaya, A. A. Andreiko, M. I. Kodess, I. A. Litvinov, O. G. Sinyashin, O. N.

Аннотация: The reactions of 3-aryl-1,2,4-triazines with -aminovinyl ketones or ethyl -aminocrotonates in acetic anhydride at room temperature afforded cyclic products of the tandem nucleophilic addition, viz., 3a,4,7,7a-tetrahydro-1H-pyrrolo[3,2-e]-1,2,4-triazines, in good yields. Under oxidative conditions, the latter compounds underwent the pyrrole-ring opening under the action of potassium permanganate to form the corresponding triazinones and were transformed into thriazolyl-substituted pyridines under the action of selenious acid

SYNTHETIC METHODS -- CROSS-COU­PLING -- NITROGEN HETEROCYCLES
Аннотация: The combination of the Suzuki–Miyaura cross-coupling and nucleophilic aromatic substitution of hydrogen reactions is a versatile tool for the syntheses of 4-(1R-pyrrol-2-yl)- and 4-(1R-indol-3-yl)-5-(hetero)aryl-substituted pyrimidines from commercially available 5-bromopyrimidine. The SNH [AE, (addition–elimination)] and SNH [AO, (addition–oxidation)] reactions of 5-bromopyrimidine with pyrroles and indoles were studied by gas chromatography–mass spectrometry. The structures of the intermediate σH adducts as well as the pyrrole-(hetero)arylpyrimidine and indole-(hetero)arylpyrimidine dyads were established for the first time by X-ray crystal structure analysis

METHYLENE GROUP -- BENZODIAZINIUM CATIONS -- ESTERS
Аннотация: The reaction of imido esters that contain an active methylene group with four isomeric benzodiazinium cations, viz., the 1-methylquinoxalinium, 2-methylcinnolinium, 3-methylquinazolinium, and 2-methylphthalazinium cations, was investigated. The 1-methylquinoxalinium cation reacts with imido esters via a scheme involving anionic [3- +2]-cycloaddition to form tetrahydropyrrolo[2,3-b]quinoxalines. The 2-methylcinnolinium cation forms an adduct with an annelated pyrrole ring. Under the influence of imido esters, the 3-methylquinazolinium cation undergoes recyclization to a 2,3-disubstituted quinoline. The 2-methylphthalazinium cation is inert in this reaction

N-METHYLTETRAHYDROQUINOXALINES -- PYRROLE -- IMIDAZOLE
Аннотация: 1H and 13C NMR spectral data for 21 N-methyltetrahydroquinoxalines annelated with furan, pyrrole, imidazole or thiazole rings are reported. Unambiguous assignments of the ring junction 13C resonances were made on the basis of selective decoupling experiments and with the aid of one-bond and long-range 13C–1H coupling constants. The effects of five-membered heterocycles on the 1H and 13C chemical shifts of the ring junction hydrogen and carbon atoms are considered. Values of one-bond 1J(CH) and vicinal 3J(HH) coupling constants between the ring junction protons are also discussed as a diagnostic means for structural elucidation of tetrahydroquinoxalines condensed with five-membered heterocycles.

Аннотация: In this paper we wish to report a highly selective and benign method for the double C-H/C-H coupling of azaaromatics with indoles or pyrrole in the presence of air oxygen/TiO2, as an effective photocatalytic oxidative system. It has been shown that this versatile approach can be applied for direct C-H functionalisation of a variety of azaaromatic systems, such as mono-, di- and triazines, substituted and unsubstituted azines and their benzo-annelated analogues.

Аннотация: The literature data on the o-cyclisation reactions of azines with 1,3-bifunctional nucleophiles, which make it possible to annelate furan, pyrrole, imidazole, and other five-membered rings to an aromatic aza-ring are surveyed and described systematically. The cyclisation reactions leading to m-linked cyclic adducts or products of the transformation of azines via the intermediate formation of cyclic m- and p-adducts are also examined.

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.
