TL;DR: A series of thiazoles (III and (V), 1,3-thiazines (IX), and thiazolidine (VII) was prepared in the presence of an environmentally friendly basic chitosan-grafted poly(vinylpyridine) catalyst as discussed by the authors.

TL;DR: In this paper, two series of novel 2-methyl-1-phenyl-5-substituted-1H-pyrazol-4-yl)ethylidene]hydrazono]-hydrazine-carbodithioate and thiosemicarbazide derivatives were prepared from reaction of hydrazonoyl halides with methyl 2-[1-(5-methyl]-1-phenyl-1,phenyl]-1,phexane]-hexane derivatives, respectively.

TL;DR: The cytototoxic activities of the thiazole derivative 5a was evaluated against HaCaT cells (human keratinocytes) and it was found that compound 5a possess potent cytotoxic activity.

TL;DR: In this paper, a series of 4-substituted 5-arylazo-2-[1-(pyrrol-3-yl)ethylidenehydrazinyl]-2,3-dihydrothiazol-3amines was prepared by cyclocondensation of α-oxohydrazonoyl halides with 1-(pyl-3yl)-ethylidenethiosemicarbazide and 1-(polyvinylpyridine), respectively.

TL;DR: Microwave-assisted synthesis of some novel compounds, namely, 3-(2-methyl-1H-indol-3-yl)-6-aryl[1,2,4]triazolo[3,4-b][1,3, 4]thiadiazoles 5a,b was accomplished via bromination of 2- methyl-3-[4-(arylideneamino)-5-mercapto-4H-[1, 2,4
