AbstractStarting from disodium 5-cyanoisothiazoledithiolate som e new substituted derivatives of the tetrathiafulvalene and some metal 1,2-dithiolenes with at least an isothiazolo-ring have been prepared. From these com pounds a number of conductive cation radical salts have been obtained.

The synthesis of 1,1,1-trichloro-2,2-bis-(p-cyanophenyl)-ethane was carried out with the condensation product of chloral and toluene as starting material. This product was converted, through the corresponding tetraacetate, to 1,1,1-trichloro-2,2-bis-(p-aldehydophenyl)-ethane which in turn reacted with hydroxylamine to give the dioxime. The subsequent dehydration of the latter gave rise to the desired dinitrile. The corresponding dichloro derivatives of the oxime and nitrile were also prepared.


In pursuing our investigation out the antimony analogues of certain nitrogen ring-systems, we Lave now succeeded in obtaining derivatives of dilhydrostibacridines, of when some of the corresponding arsenic compounds have been studied recently by Gump and Stolzenburg. The starting material for the work was o -aminodiphenylmethane obtained from the corresponding nitro derivative when, in turn, was prepared from o -nitrobenzyl chloride and benzene by Taneseseu's modification of the Friedel-Crafts reaction.

The natural product lupeol (1) was isolated from Bombax ceiba leaves, which were used as starting material in the semisynthetic approach. Three new derivatives (2a, 2b, and 3) were synthesized using oxidation and aldolization. Their chemical structures were elucidated by spectroscopic analyses (HRESIMS and NMR). Compounds 3 showed significant α-glucosidase inhibition with an IC50 value of 202 µM, whereas 2a and 2b were inactive.

Abstract4-Hexyloxycarbonyl-, 4-dodecyloxycarbonyl- and 4-hexadecyloxycarbonyl-N-hydroxyphthalimides were synthesised using trimellitic anhydride chloride as the starting material. The obtained lipophilic derivatives of N-hydroxyphthalimide were applied as catalysts of the cumene oxidation reaction with oxygen performed in polar acetonitrile, in non-polar tert-butylbenzene and in the absence of a solvent. The courses of reactions catalysed by N-hydroxyphthalimide and its derivatives were compared.

Reduction of 4-cyclopentylacetophenone oxime gave the title compound II which was transformed by a combination of acylation, alkylation, reduction and substitution reactions to compounds III-XI. 2-Benzylcyclopentanone oxime was reduced to 2-benzylcyclopentylamine (XVI) and converted by a reaction with methylmagnesium iodide and by the following Ritter reaction to the formamide derivative XVIII which was used as the starting material for preparing amines XIX-XXI. The local anaesthetic and spasmolytic activity were the most typical neurotropic effects of derivatives of compound II. 2-Benzyl-1-methylcyclopentylamine and derivatives XIX-XXI have some hypotensive activity.
