Expansion of nalidixic acid ( NA) has been accomplished by linear insertion of a benzo-ring between the two pyrido moieties. The resulting compounds exhibit antibacterial activity comparable to NA and are highly fluorescent. The regioselective hydrogenation of 1,7-phenanthrolines was studied. [ABSTRACT FROM AUTHOR]

The following groups of title substances according to general formula I where prepared: substituted α, α-diphenyl-2-thenyl-derivatives (mainly of heterocyclic secondary amines), chlorinated α-phenyl-α-(2-thienyl)-4-pyridinemethanoles and substituted (mainly chlorinated) tri- and tetraphenylmethanes. [ABSTRACT FROM AUTHOR]

A group of N-substituted 2-aminoacylamino-4,5,6,7-tetrahydro-benzo[ b]thiophene-3-carbonitriles ( 1) was prepared from 2-amino-4,5,6,7-tetrahydro-benzo[ b]thiophen-3-carbonitrile ( A). Cyclisation reactions using A and N-heterocyclic analogues thereof ( A and B) as starting materials gave derivatives of the following two new heterocyclic ring systems: [1]benzo-thieno[3,2- e][1,2,4]-triazolo[2,3- c]pyrimidine ( B) and pyrido-[4′,3′∶4,5]thieno[3,2- e][1,2,4-triazolo][2,3- c]pyrimidine ( C). [ABSTRACT FROM AUTHOR]

Derivatives of [1]benzothieno[2.3- c]pyrazole, a new heterocyclic ring system, were synthesized by 1.3-dipolar cycloadditions: benzo[ b]thiophene-1.1-dioxide and derivatives thereof reacted with diazomethane and diazoethane to yield substituted [1]benzothieno[2.3- c]pyrazolines. A similar reaction with ethyl diazoacetate gave the corresponding cyclopropa[ b][1]benzothiophene-2.2-dioxide derivative. [ABSTRACT FROM AUTHOR]

3-Halogeno-2-phenyl-benzo[ b]thiophene-1.1-dioxide and 2-bromo-3-phenyl-benzo[ b]thiophene-1.1-dioxides reacted with open-chain and heterocyclic amines to the corresponding title substances. [ABSTRACT FROM AUTHOR]

Cyclisation of 2-(β-oxo-alkylthio)-thieno[2.3- d]pyrimidin-4(3 H)-ones gave separable mixtures of the title substances and their [2.3- b]-isomers. The structure of the two isomers were be proved by comparison with a linear product synthesized by an unambiguous method. Similar cyclisations were achieved by reactions of 2-mercapto-thieno[2.3- d]pyrimidin-4(3 H)-ones with chloroacetone, 1.2-dibromoethane or 1.3-dibromopropane. [ABSTRACT FROM AUTHOR]

The title substances and their [1]benzothieno analogues were synthesized by reaction of 3-allyl-2-mercapto-([1]benzo)thieno-[2.3- d]pyrimidine-4(3 H)-ones with Br to 2-bromomethyl-2.3-dihydro-thiazolo[3.2- a]([1]benzo-)thieno[2.3- d]pyrimidine-5-ones, which on treatment with morpholine did not give the corresponding morpholine derivatives but elimination to the exocyclic double bond. These 2-methylene-2.3-dihydro-products were isomerized by HSO to the corresponding 2-methyl compounds. [ABSTRACT FROM AUTHOR]

Derivatives of 1 H-[1]Benzothieno[3,2− c]pyrazole were synthesized by a new method: 1.3-dipolar cycloaddition of substituted benzo[ b]thiophene-1.1-dioxides with C-methyl-N-phenyl and C,N-diaryl-nitrilimines, resp., gave the corresponding title compounds. The structure was proved by conversion to known compounds. [ABSTRACT FROM AUTHOR]

Catalytic hydrogenation of 2.3-dihydro-thieno[2.3− f]-quinoline-1.1-dioxide yielded 2.3.6.7.8.9-hexahydrothieno-[2.3− f]quinoline-1.1-dioxide, which was substituted via the corresponding chloroacyl compounds to several 6-aminoacyl-derivatives. Skraup's synthesis using 6-amino-2.3-dihydro-3-morpholino-benzo[ b]thiophen-1.1-dioxide gave 2.3-dihydro-3-morpholino-thieno[2.3− f]quinoline. [ABSTRACT FROM AUTHOR]

Addition of Br to the exocyclic double bond of 2-methylene-2.3-dihydro-thiazolo[3.2− a]thieno[2.3− d]pyrimidine-5-ones and-[1]benzothieno[2.3− d]pyrimidine-5-ones, followed by elimation of HBr gave the corresponding 2-bromomethylthiazolo-compounds, which reacted with secondary amines to 2-(dialkylamino-methyl)-thiazolo[3.2− a]-([1]-benzo)-thieno-[2.3− d]pyrimidine-5-ones and their heterocyclic analogues. [ABSTRACT FROM AUTHOR]

Reaction of 2-methylthio-thieno[2.3- d]pyrimidin-4(3 H)-ones with heterocyclic secondary amines, ethanolamine and hydrazine, resp., gave the corresponding derivatives with a basic substituent in position 2. Cyclization of the hydrazino compounds with formic acid gave derivatives of thieno[2.3- d]-1.2.4-triazolo[4.3- a]pyrimidine and [1]benzothieno[2.3- d]-1.2.4-triazolo[4.3- a]pyrimidine, two new heterocyclic systems. [ABSTRACT FROM AUTHOR]

For the so-called 'conditioned' distribution functions, derived from the distribution functions used in the BBGKY-hierarchy, a certain ansatz is made, the consequences of which are investigated. As an application a simple example is discussed, namely the problem of the charge distribution around an ionized particle in presence of an external electrical field. [ABSTRACT FROM AUTHOR]

The wellknown derivation of Fresnel's formula for the reflection coefficient of a metal surface in the case of an oblique incident wave polarized parallel to the plane of incidence includes a mistake concerning the boundary conditions and neglecting the possibility of optical excitation of plasma waves. The right formula for this case is derived in the following paper by Forstmann. The discussion of an approximate formula obtained by a simplified method leads in the case of vanishing reflectivity for Ω>Ω to a real Brewster-angle α. For Ω<Ω there exists another solution with a complex Brewster-angle, representing a surface wave in form of a Zenneck-wave. For large wave numbers and for light velocity ≫ electron velocity the dispersion formula for these surface waves is nearly identical with that obtained by Ritchie and Wagner, while for small wave numbers there is a great difference between these two formulas. In the middle region the frequence Ω is nearly Ω/√2. [ABSTRACT FROM AUTHOR]

Derivatives of [1]benzothieno[2.3- d]isoxazole, a new heterocyclic ring system, were synthesized by 1.3-dipolar cyclisations: benzo[ b]thiophene-1.1-dioxide and its 3-methyl derivative reacted with nitrile oxides and nitrones to the corresponding substituted [1]benzothieno[2.3- d]isoxazolines and-isoxazolidines. Hydrogenolysis of the latter cleaved the isoxazolidine ring, yielding the corresponding 2-(α-phenylamino-benzyl)-3-hydroxy-2.3-dihydro-benzo[ b]thiophene-1.1-dioxides. [ABSTRACT FROM AUTHOR]

Derivatives of 5 H-thiazolo[3.2− a]thieno[2.3− d]pyrimidine( A), 5 H-[1]benzothieno[2.3− d]thiazolo[3.2− a]pyrimidine ( B), 4 H-thiazolo[3.2− a]thieno[3.2− e]pyrimidine ( C) and 5 H-[1]benzo-thieno[3.2− e]thiazolo[3.2− a]pyrimidine ( D) were synthesized by various methods. Similar reactions are leading to derivatives of thieno[2′.3′∶4.5]pyrimido[2.1− b][1.3]thiazine ( E) and [1]benzothieno[2′.3′∶4.5]pyrimido[2.1− b][1.3]thiazine ( F). C, D, E, and F are new heterocyclic ring systems. Detailed papers will appear soon. [ABSTRACT FROM AUTHOR]

The title substances, derivatives of two new heterocyclic ring systems, were synthesized by intramolecular cyclisations of diazonium compounds, prepared from derivatives of 2-amino-thiophene-3-carboxamide and of 2-amino-benzo[ b]thiophene-3-carboxamide. By-reactions and substitution reactions are mentioned. [ABSTRACT FROM AUTHOR]

2-Mercapto-thieno[2.3- d]pyrimidine-4(3 H)-one, 2-mercapto-5.6.7.8-tetrahydro-[1]benzothieno[2.3- d]pyrimidin-4(3 H)-one and derivatives thereof were synthesized by cyclisation of esters or amides of the corresponding 2-amino-thiophene-3-carboxylic acids: either by direct reaction with thiourea or by reaction with methyl- or allyl-isothiocyanate via the corresponding N,N′-disubstituted thioureas as intermediates.
