The monitoring by UV spectroscopy of the Pd-catalyzed hydrogenolysis in acetonitrile of 2-methyl-2-benzyloxycarbonyl-1-indanone and 2-methyl-2-benzyloxycarbonyl-1-tetralone showed the successive formation of corresponding beta-ketoacids and enols to deliver finally the ketones. Some factors which influence the stability of the intermediates are determined.(More)
The two new gem-dihalogenocyclopropanes (1'S,3R)-3-(2',2'-dichloro-1'-methylcyclopropyl)-6-oxoheptanoic acid, C(11)H(16)Cl(2)O(3), (2), and (1'S,3R)-3-(2',2'-dibromo-1'-methylcyclopropyl)-6-oxoheptanoic acid, C(11)H(16)Br(2)O(3), (3), are isostructural. Both present two stereogenic centers at C1' and C3. The absolute configuration was determined by X-ray(More)
The title compound, C13H19N3OS, is a new thia-zolidin-4-one derivative prepared and isolated as the pure (3aS,6R)-diastereisomer from (R)-thio-semicarbazone pulegone. It crystallized with two independent mol-ecules (A and B) in the asymmetric unit. The compound is composed of a hexhydro-indazole ring system (viz. a five-membered di-hydro-pyrazole ring fused(More)
The crystal structure and the conformation of the title compound, C22H27N3O7S, were determined from the synthetic pathway and by X-ray analysis. This compound is a new 4-thia-zolidinone derivative prepared and isolated as pure product from thio-semicarbazone carvone. The mol-ecule is built up from an oxo-thia-zolidine ring tetra-substituted by a(More)
The synthesis and characterization of new N-donor bitriazolic tripods were reported. The in vitro antibacterial and antifungal activities of these products were screened against fungal strain (Candida pelliculosa) and against four bacterial strains (Micrococcus luteus, Bacillus subtilis, Listeria innocua and Escherichia coli). Biological data revealed the(More)
