    Notizen: Summary The binding of semi-synthetic (16α-gitoxin and its 16-acetate) and naturally occurring cardioactive glycosides (digitoxin, ouabain) to human serum albumin was studied using equilibrium dialysis, ultracentrifugation and gel filtration. 16α-gitoxin was 75% bound and its 16-acetate 95%. The percentage binding of digitoxin and ouabain was in good agreement with values reported in literature.

    Notizen: Reaction Behaviour of Amides with Carbondisulphide and IsothiocyanatesReactions of substituted arylamides, hetarylamides and furylacrylicamide 1 with carbon disulphide present a possibility to synthesize imino-dithiocarbonic-S,S′-diester 5. The mechanism of the reaction and the reaction conditions are investigated. Quantum chemical investigations by simple HMO-method in connection with the experimental results describe the reaction in dependence upon the influence of substituent in 2- and 4-position to the phenylring. Further more is described the reaction of amide with isothiocyanates to thiourea 6 and isothiourea 7.The structures of the final products are determined by analytical dates.

    Notizen: Synthesis and Reaction Behaviour of N-(3-Chlorobenzo[b]thiophene-2-carbonyl)-imino-dithiocarbonic Derivatives3-Chlorobenzo[b]thiophene-2-carbonyl-chloride 1 was treated with potassium rhodanide to afford the appropriate acyl isothiocyanate 3, which adds nucleophilic agents as amines and thioles in good yields.Addition of methanethiole and subsequent alkylation of the dithiocarbamate 7 gives S, S-dimethylimino-dithiocarbonate 8. 3-Chlorobenzo[b]thiophene-2-carboxamide 2 reacts with carbon disulphide and phenyl isothiocyanate by chlorine substitution and cyclisation to benzo[b]thieno[2, 3-e]thiazines 9, 10 or 11. The structure of the final products were determined by analytical and spectroscopical dates.

    Decay channels of core excitation resonances in 3d and 4f metal atoms (1986)

    Notizen: Abstract Photoabsorption, photoelectron, and ejected electron spectra of atomic 3d metals and rare earths in the energy range of the strong 3p→3d and 4d→(4fεf) excitations are presented. TheZ-dependence of the strength, shape and decay channels of the giant resonances is discussed. With increasing Z for the 3d metals the 3p→3d resonances change from almost symmetric lines close to the 3p-ionization limits to broad asymmetric profiles centered well below the 3p-ionization threshold. Autoionization leading to the emission of a 3d electron dominates the decay. For lowZ rare earths the 4d→(4fεf) resonances mainly decay via the emission of a 4d electron whereas for higherZ the emission of a 4f electron takes over.

    Notizen: Reactions with N-Acylimino-dithiocarbonic-acid-diesters.Reactions of N-acylimino-dithiocarbonic-acid-S,S-diesters 1 with nucleophilic com-pounds present new possibilities to synthesize heterocycles. With amines 1a reacts by mono- and disubstitution, respectively, of methylthio-groups to isothioureas 2 and guanidines 3, with 1,2-bi-nucleophilic arenes to benzoheterocycles 4, with aliphatic diamines to imidazolidines 5, pyrimidines 6, diazepines 7 and the hexamethylene-diamine-derivatives 8. 1a reacts also with hydrazines to 1,2,4-triazoles 9 and with hydrazides to the thiosemicarbazones 10 or 1,3,4-oxadiazoles 11. Heterocyclisations of 1 with guanidines, thiourea, salts of thiourea and amidines give the 1,3,5-triazines 12, 14, 15 and 16. N-benzoyl-dithiocarbonic-acid-methylester -amid reacts with CH-acidic compounds to thiazoles 17. The structures of the final products are determined by i.r.-, 1H-n.m.r.-, u.v.- and mass-spectras.

    Notizen: New Synthesis of Dimethyl-cinnamoylimino-dithiocarboxylate and Reactions with NucleophilesA new general synthesis of dimethyl-cinnamoylimino-dithiocarboxylate 1d is possible by reaction of 4-nitro-cinnamoylamide with carbon disulfide in the presence of sodium hydride and following alkylation. With the unsubstituted dimethyl-cinnamoylimino-dithiocarboxylate 10 is in-vestigated the reaction behavior with nucleophilic compounds. The treatment of 1c with primary amines, respectively, by mono- and disubstitution of the methylthio groups yields isothiourea 2 or guanidines 3. Benzocondensed heterocycles are formed by reaction of 1c with o-bifunctional nucleo-philes.The compounds 5, 6 and 7 have been synthesized from 1c with cysteamine, p-phenylenediamine and ethylenediamine.The oxadiazole 8 and isothiosemicarbazide 9 are obtained by reaction of the dithioester 1c with hydrazides. On the other hand cyclisation to the 1,2,4-triazole 11 over the intermediate 10 and to the 1,3,5-triazine 12 are possible.The reaction of 1c with carbanions in a basic medium affords acrylic derivatives 13.In the same way we isolated by reaction of dithioester 1c with a benzothiazolium salt the dark coloured compound 14. The physical properties of synthesized compounds are discussed by mass-, 1H-n.m.r.-, i.r.- and u.v.-spectra.
