Furan derivatives. ЬХХП. Synthesis and some properties of l-(5-nitro-2-furyl)- -2- (5-aryl-2-furyl)ethylenes
Wittig reaction has recently been applied also in the preparation of 5-nitrofuran derivatives of ethylene [1—5]. The quoted syntheses were accomplished starting either from 5-nitrofurfuryl halides which were converted into 5-nitrofurfurylidenephosphoranes and subsequent condensation of the latter with carbonyl compounds [1—4], or the intermediate phosphoranes were prepared from other furfuryl h...
متن کاملSynthesis and in vitro Anti-Bacterial Activity of 2-(5-Nitro-2-heteroaryl)-1,3,4-Thiadiazole Derivatives
A new series of 2-(5-nitro-2-heteroaryl)-1,3,4-thiadiazole derivatives, including nitro furan, nitro thiophene and nitro imidazole, were synthesized and screened in vitro for their inhibitory activity against eight bacterial strains. The results showed that most of the synthesized compounds were active against Gram-positive bacteria, determined by MIC method. Among them, compounds <str...
متن کامل2-Amino-5-nitro-N-[(E)-thiophen-2-ylmethylidene]aniline
In the title mol-ecule, C(11)H(9)N(3)O(2)S, the thio-phene and benzene rings form a dihedral angle of 17.68 (9)°. The thio-phene S atom and the imine N atom are syn with respect to each other. In the crystal, N-H⋯O and N-H⋯N hydrogen bonds connect mol-ecules, forming a two-dimensional network parallel to (10-1).
متن کاملAntiprotozoal thiazoles. 2. 2-(5-Nitro-2-furyl-, thiazolyl-, and 1-methylimidazolyl-)thiazoles.
Ten 2-substituted 4-thiazolecarboxaldehyde hydrazones bearing 5-nitro-2-furyl, 5-nitro-2-thiazolyl, and 1-methyl-5-nitro-2-imidazolyl functions have been prepared and screened for activity against Trypanosoma cruzi infections in mice. The results permitted the ranking of these substituents in decreasing order of activity: 1-methyl-5-nitro-2-imidazolyl greater than 5-nitro-2-furyl greater than 5...
متن کاملStatistical analysis on toxicity of a nitrofuran derivative, 2-(2-furyl)-3-(5-nitro-2-furyl)acrylamide.
A food additive, furylfuramide or AF-2, which had been used in Japan since 1965 and structurally is composed of 5-nitro-2-furyl radical and acrylamide, was re-examined mainly on chronic toxicity by statistically reviewing published data. The conclusions are as follows: 1) The maximum safety dosage which shows no demonstrable change in rats must be corrected at least to 1/170 of the value which ...
