The general part of the experimental section [1] has been presented elsewhere. To a boiling solution of 4,5-dimethoxy-4-nitrobenzophenone (10.0 g, 35 mmol) in ethanol (85 ml), NaBH4 (0.61 g) was added gradually.
A solution of 5-nitroisophthaloyl dichloride (1) [1] (3.92 g, 15.8 mmol) and 4-tert-butylbenzhydrazide (2) [2] (6.08 g, 31.6 mmol) in CHCl3 (70 mL) was heated to reflux for 12 h.[...]
The reduction was carried out as described in reference [1] by using a mixture of sulfur (7.10 g, 0.22 mol), Na2S — 9 H2O (240 g, 0.22 mol), water (140 mL) and pyridine (20 mL).[...]
Synthesis of purines and purine mono-1-oxides from the respective 5-substituted 4-nitroimidazole derivatives is described. The commercially available 4-nitroimidazole, in a few simple steps (including Vicarious Nucleophilic Substitution of Hydrogen),...
The title 3-amino-2-thiohydantoins 3 has been prepared in very good yields by the reaction of alkyl isothiocynatocarboxylates 1 with hydrazine hydrate.The synthesis of starting isothiocyanates as well as spectral data of 3-aminothiohydantoins and alk...
The thermal and acid-catalyzed intramolecular rearrangement of the (Z)- and (E)-cyclodecene-1,4-dione compounds deriving from steroids, 2a,b and 3a,b, respectively, proceeds stereoselectively to give the corresponding configurationally different spir...
Substitution of 4-methyl-[1,8]-naphthyridine in 2 and 7 position by alkylamines leads to highly fluorescent compounds. The arrangement of hydrogen donor and acceptor groups of these naphthyridines allows interactions with guanine and guanine cytosine...
