The tandem AN—AN reactions of 2,3-dicyano-1-ethylpyrazinium tetrafluoroborate with 1,3-diketone enolates or keto esters afforded tetrahydrofuro[2,3-b]pyrazine derivatives, whereas cyclization with ethylene glycol gave tetrahydro-1,4-dioxino[2,3-b]pyrazine.

INDOLO[3,2-B]CARBAZOLE -- INDOLE -- THIOPHENE
Аннотация: Novel 5,11-dialkyl-6,12-di(thiophen-2-yl) substituted 5,11-dihydroindolo[3,2-b]carbazoles have been obtained and plausible ways for their further modifications via the Friedel–Crafts reaction are presented. The formylation of these indolo[3,2-b]carbazoles with dichloromethyl alkyl esters catalysed by Lewis acids leads to the formation of the corresponding 2,8-diformyl derivatives. Applicability of this formylation method for modification of indolo[3,2-b]carbazoles bearing electron-rich aromatic substituents at C-6 and C-12 has also been demonstrated. The Knoevenagel condensation of 2,8-dialdehydes with active methylene nitriles has been studied. The measurements of optical and redox properties for a number of new indolo[3,2-b]carbazoles have been performed

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

AZINES -- BIFUNCTIONAL REAGENTS -- CYCLOADDUCTS
Аннотация: Reactions of azines with bifunctional nucleophiles can give rise to several cycloadducts, the structure depending on the nature of reagents, the structure of the azine substrate, and the reaction conditions. Three types of cycloadducts are proposed to be formed in reactions of azines with such 1,3-N,C-dinucleophiles as acetamidines and acetimino esters. Ortho-cyclization products can usually be isolated, while meta- and para-bridged cycloadducts are unstable and are often transformed into other heterocyclic systems. Their presence as intermediates can, however, often is rationalized by spectroscopic methods or 15N-labeling studies. Many of the reactions discussed provide a very convenient synthetic route to a great variety of azine derivatives. It seems to be a very interesting and promising area of heterocyclic chemistry and there is no doubt that further investigations into this field also allow new syntheses of useful compounds to be developed

5-NITROPYRIMIDINES -- CH-ACITVE NITRILES
Аннотация: Nitriles R–CH2CN where R is CN, SO2C6H5, C6H4-NO2-p, C6H4-CF3-m, are effective reagents for converting 5-nitropyrimidine (1) into 2-amino-5-nitro-3-R-pyridines (7). In reactions of 1 with cyanoacetic acid derivatives (methyl, ethyl, tert-butyl esters), 3-cyano-5-nitro–2(1H)-pyridone is formed in addition to 7. Ketonic nitriles, such as 3-oxobutyronitrile and 3-oxo–3-phenylpropionitrile, react with 1 to form 2-methyl- and 2-phenyl-5-nitro-3-cyanopyridine, respectively. Plausible mechanisms are discussed. The reaction of 1 with N-(cyanoacetyl)carbamate provides a facile synthetic route to 1,2,3,4-tetrahydro-6-nitropyrido[2,3-d]pyrimidine-2,4-dione.

FLUORINATED 1,3-DIKETONES -- ACETALS -- CLAISEN CONDENSATION -- CALCIUM HYDRIDE -- 3-(POLYFLUORACYL)PYRUVALDEHYDES -- PYRAZOLE-1h-3- CARBALDEHYDES
Аннотация: An efficient approach for the synthesis of 3-(polyfluoroacyl)pyruvaldehydes dimethyl acetals (1,1-dimethoxy-4-polyfluoroalkyl-butan-2,4-dions) from 1,1-dimethoxyacetone and polyfluorinated carboxylic acid esters has been developed. The procedure includes the Claisen type condensation of the starting materials by means of calcium hydride in methanol, followed by isolation of copper complexes of the corresponding diketones and their destroying with disodium EDTA. A simple synthesis of 5(3)-(polyfluoroalkyl)-1H-pyrazole-3(5)-carbaldehydes and their acetals is also presented.
