The 1,2,3-thiadiazole route to new vinylogue tetrathiafulvalenes

Cleavage of 1,4-dithiafulvene-substituted 1,2,3-thiadiazoles with base and dimerisation of the resulting alkyne-1-thiolate gives new tetrathiafulvalene-type vinylogue extended π-donors in a one pot reaction. The solvent-/base-system used (acetonitrile/NaH) was optimised for the synthesis of 1,3-dithiole-2-thiones via this route. Efficient synthesis of the important 4-formyl-1,3-dithiol-2-thione and its coupling to 2,6(7)-bisformyltetrathiafulvalene is presented. Preparation of a number of new 1,4-dithiafulvenes are reported.

TBAI-Catalyzed Reaction between N-Tosylhydrazones and Sulfur: A Procedure toward 1,2,3-Thiadiazole

A TBAI-catalyzed reaction between N-tosyl hydrazone and sulfur was developed, leading to 1,2,3-thiadiazoles in moderate to good yields. It represents a facile and practical procedure to access thiadiazole under metal-free conditions. This procedure serves

Synthesis, characterization, antiamoebic activity and cytotoxicity of novel 2-(quinolin-8-yloxy) acetohydrazones and their cyclized products (1,2,3-thiadiazole and 1,2,3-selenadiazole derivatives)

A series of 1,2,3-thiadiazole and 1,2,3-selenadiazole derivatives were synthesized by the cyclization of novel 2-(quinolin-8-yloxy) acetohydrazones. In vitro antiamoebic activity was performed against HM1: IMSS strain of Entamoeba histolytica. The results showed that all the 2-(quinolin-8-yloxy) acetohydrazones were more active than their cyclized products (1,2,3-thiadiazole and 1,2,3-selenadiazole derivatives). SAR showed that the compounds having quinoline ring and hydrazone linkage with free N-H group are responsible for higher antiamoebic activity. The cytotoxic studies of these compounds on human breast cancer MCF-7 cell line showed that all the compounds were nontoxic at the concentration range of 1.56-50 μM.
