NITROIMIDAZOLES XI [I]. SYNTHESES OF DISUBSTITUTED NITROIMIDAZOLYLQUINOLINES
Reaction of substituted-aniline (8) with ethyl (l-methyl-5-nitroimidazole-2- carbonyl) acetate (9) gave 4-hydroxy-2-(l-methyl-5-nitro-2-imidazolyl)- substituted-quinolines (lo), which were converted to compound 11 with phosphorus oxychloride. Substituted-2-(l-methyl-5-nitro-2-imidazo1yl)-4.- methyl-(or phenyl-) quinolines (14) were prepared through the reaction of 2- acetyl-5-nitro-1-methy...

متن کاملGroove-binding unsymmetrical cyanine dyes for staining of DNA: syntheses and characterization of the DNA-binding.
Two new crescent-shaped unsymmetrical cyanine dyes have been synthesised and their interactions with DNA have been investigated by different spectroscopic methods. These dyes are analogues to a minor groove binding unsymmetrical cyanine dye, BEBO, recently reported by us. In this dye, the structure of the known intercalating cyanine dye BO was extended with a benzothiazole substituent. To inves...
متن کاملResearch on Syntheses and Properties of Water-soluble Symmetrical Squarylium Double-cyanine Dyes
In this paper, 2,3,3-trimethyl-3H-indolin was synthesized by phenylhydrazine and 3-methyl-2-butanone as raw materials in the acetic acid reacted with different nitrogenalkylating reagents. Semi mono-cyanine dye and semi dicyanine dye were prepared with the help of squaric acid diethyl ester. The spectral properties of the target products were checked. The results show that compared with symmetr...

In this paper, 2,3,3-trimethyl-3H-indolin was synthesised by phenylhydrazine and 3-methyl-2-butanone as raw materials in the acetic acid, and then was reacted with different nitrogen lkylating reagents. The two kinds of conducts acted with squaric diethyl ester respectively to prepare mono-semicynine dye and dis-semicyanine dye. The spectral properties of the target products were checked. The r...
