A novel method for the synthesis of 2,5-diarylselenophenes
摘要:
The reaction of 4-phenyl- or (2-thienyl)-1,2,3-selenadiazoles with 10 equiv. of arylacetylenes leads to the formation of 2,5-diarylselenoplienes in moderate to good yields and 1.4-diarylbuta-1,3-diynes as by-products. (C) 2002 Elsevier Science Ltd. All rights reserved.
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)
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

3-selenadiazoles was achieved using an ionic liquid as a novel soluble support. Ionic liquid-supported sulfonyl hydrazine was synthesized and reacted with a number of ketones to afford the corresponding ionic liquid-supported hydrazones that were converted to 1,2,3-thiadiazoles in the presence of thionylchloride. The reaction of ionic liquid-supported hydrazones with selenium dioxide in acetonitrile afforded
