A novel class of anion receptors with with C-H···X- hydrogen bonding is introduced and demonstrated for Cl-, Br-, NO3- and HSO4- recognition. Cyclic voltammetry revealed that novel ferrocenylimidazolium salts, syntheses of which are briefly described...

A fast and simple method for the oxidative iodination of some aromatic amines, under microwave irradiation, is reported, using diiodine and the the strongly Hbonded urea-hydrogen peroxide addition compound (H2NCONH2···H2O2, UHP) as the oxidant. The r...

Three new heterocyclic substituted dianilides, namely 3-chloro-5-[1-(pfluorophenylcarbamoyl)-2-(2-thienyl)ethenyl]thieno-[3,2-b]thiophene-2-carboxy-p-fluoroanilide (8), 1,2-bis{5-[2-(p-fluorophenylcarbamoyl)-2-(2-thienyl)ethenyl]-2-thienyl}ethene (13...

A number of chalcones were prepared by condensing either 1-acetylnaphthalene or substituted 1-acetylnaphthalenes with 1-naphthaldehyde or 4-dimethylamino-1-naphthaldehyde in ethanolic NaOH solutions. These chalcones were immediately reacted with hydr...

A fluorimetric assay of aldehyde dehydrogenase isozymes, based on naphthaldehyde oxidation, is compared with Western Blotting analysis on several clinical samples obtained from surgery. The comparison reveals qualitatively good correlation of ALDH1A1...

Two alternative and complementary one-pot procedures for the direct transformation of 2-amino alcohols to N-tosyl aziridines are presented. The unsubstituted parent compound and its less hindered homologues can be obtained in high yields by tosylatio...

3-(4-Substitutedphenyl)aminoisoxazol-5(2H)-ones, substituted on nitrogen with a nitropyridine group, react with triethylamine to give imidazo[1,2-a]pyridines and indoles. With 4-bromophenyl and 4-methylphenyl group substituents only imidazopyridines...
