NITROIMIDAZOLES XI1 [I]: SYNTHESES OF TRISUBSTITUTED PYRAZOLES AND SUBSTITUTED (1 -METHYL-5-NITRO-2- IMIDAZOLYL) PYRIMIDINONES
The reaction of P-diketones 1 with phenyl hydrazine afforded 5-aryl-3-(1- methyl-5-nitro-2-imidazoly1)-1-phenylpyrazole (2) and 3-aryl-5-(1-methyl-5- nitro-2-imidazoly1) -1-phenylpyrazole (3). The reaction of diketones (1) with urea in the presence of p-toluenesulfonic acid gave 4-(or 6-)aryl-6-(or 4-)(1-methyl- 5-nitro-2-imidazolyl)-1-(lH)pyrimidones (4). The structures of all compounds w...

متن کاملSELENIUM HETEROCYCLE XL II [1]. SYNTHESES OF SUBSTITUTED THIAZOLO, SELENAZOLO AND 1,2,3-SELENADIAZOLOINDOLES
Reaction of compound 1 with thiobenzarnide or substituted selenobenzamides afforded substituted pyrrolobenzothiazole or selenazoles (2) respectively. Selenium dioxide oxidation of the semicarbazone 4 with selenium dioxide gave 6- benzenesulfonyl- 4,5-dihydro-pynolo [3,2-el benzoselenadiazole (5).
متن کاملExcited state proton transfer of some substituted naphthols in liposomes
Fluorescence probes based on excited state proton transfer (ESPT) have been recently developed for microheterogeneous media. The ESPT behaviour of a series of substituted naphthols (4-chl oro-1-naphthol, 5-amino-1-naphthol , 4-methoxy1-naphthol, 7-methoxy-2-naphthol , 3-amino-2-naphthol, 6-bromo-2naphthol and 1-bromo-2-naphthol) is investigated in liposomes, using steady state and time resolved...
متن کاملSYNTHESES, ANTIFUNGAL AND ANTIBACTERIAL ACTIVITIES OF SUBSTITUTED 1,2, CTRIMOLES
The reaction of readily available 1 -methyl-4-nitropyrrole-2- carboxylic acid (1) with thionyl chloride afforded the corresponding acyl chloride 2. The reaction of compound 2 with thiosemicarbazides yielded 1-(1 -methyl-4-nitrop yrrole-2-carbony1)- thiosemicarbazides (3) which cyclized in basic medium to 5-(1-methyl-4-nitropyrrole- 2-y1)-2,4-dihydro-3H- l,2,4-triazole-3- thione 4. Alkylatio...
