- Bismuth chloride mediated synthesis, antimicrobial, and anti-inflammatory activities of new 4-aryl-2-amino thiazoles
-
Synthesis of 4-aryl-2-Amino thiazoles (3a-u), (4a-c), and (5a-c) was achieved from the reaction of 4-butyl phenacyl chlorides (2a-c) with N-substituted thioureas, in the presence of Bismuth Chloride. The antimicrobial and anti-inflammatory activities of the final products were also studied. Copyright Taylor & Francis Group, LLC.

- Aminothiazoles: Part 1 - Syntheses and pharmacological evaluation of 4-[isobutylphenyl]-2-substituted-aminothiazoles
-
Unreported p-isobutyl phenacyl chloride has been prepared by the reaction of chloroacetyl chloride on isobutyl benzene. It is condensed with thiourea and its derivatives to get the title compounds. The products obtained are characterized by their IR, sup

- Process for preparing α-hydroxy-acids and compounds obtained by this process
-
The invention relates to a process for preparing α-hydroxy-acids of general formula: STR1 in which R represents hydrogen or a lower alkyl radical and Cy represents a phenyl, naphthyl or heterocyclic radical, these latter three radicals optionally comprising one or more substituents selected from the group consisting of lower alkyl, lower alkenyl, lower alkynyl, lower alkoxy radicals and halogen atoms, process which comprises the treatment of an α-monohalogenated ketone of general formula: STR2 in which R and Cy have the same meaning as above and X represents chlorine, bromine or iodine, in the presence of an aqueous solution of an alkali metal hydroxide, a non-polar organic solvent selected from an aromatic or alicyclic hydrocarbon and oxygen in excess optionally in the presence of an inert gas, the treatment being carried out at a temperature ranging from the boiling temperature of the reaction medium at atmospheric pressure and 240° C. under pressure and the alkali metal so formed is then acidified to obtain the desired acid.
