Novel 3-acetoacetylaminobenzo[b]furan derivatives having a modified triene system at the 3-position were synthesized starting with 3-aminobenzo[b]furans. The enol isomers, 3-[(3-hydroxybul-2-enonyl)amino]benzo[b]furans (1), of the 3-acetoacetylaminobenzo[b]furans were obtained as stable isomers owing to formation of a hydrogen bonding between the enol hydroxyl group and the amidocarbonyl group. The planarity of the C-2 substituent through the C-3 side chain suggested the existence of a modified conjugational triene system in the enol compound. Cysteinyl leukotriene 1 and 2 receptor antagonistic activities for these compounds were evaluated. 2-(4-Cyanobenzoyl or ethoxycarbonyl)-3-[(2-cyano-3-hydroxybut-2-enonyl)amino]benzo[e]furans (15g, 15o, 15u) were moderately active.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. Formula: C8H2F2O3. Introducing a new discovery about 18959-30-3, Name is 4,5-Difluorophthalic Anhydride

Phenylethynyl containing imide-silanes were prepared from aminoalkyl and aminoaryl alkoxy silanes and 4-phenyletbynylphthalic anhydride in toluene to form the imide in one step or in N-methyl-2-pyrrolidinone (NMP) to form the amide acid intermediate. Controlled molecular weight pendent phenylethynyl amide acid oligomers terminated with aminoaryl alkoxy silanes were prepared in NMP from aromatic dianhydrides, aromatic diamines, diamines containing pendent phenylethynyl groups and aminoaryl alkoxy silanes. The phenylethynyl containing imide-silanes and controlled molecular weight pendent phenylethynyl amide acid oligomers terminated with aminoaryl alkoxy silanes were used to improve the adhesion between phenylethynyl containing imide adhesives and inorganic substrates (i.e. metal). Hydrolysis of the alkoxy silane moiety formed a silanol functionality which reacted with the metal surface to form a metal-oxygen-silicon (oxane) bond under the appropriate reaction conditions. Upon thermal cure, the phenylethynyl group of the coupling agent reacts with the phenylethynyl functionality of phenylethynyl containing imide adhesives and becomes chemically bonded to the matrix. The resultant adhesive bond is more durable (i.e. hot-wet environmental resistance) than adhesive bonds made without the use of the coupling agent due to covalent bond formation between the phenylethynyl containing imide-silane coupling agent or the controlled molecular weight pendent phenylethynyl amide acid oligomers terminated with aminoaryl alkoxy silanes and both the metal substrate and phenylethynyl containing imide adhesives.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Formula: C8H2F2O3, you can also check out more blogs about18959-30-3

Quinolones have been discovered in our laboratory was a new class of antifilarial agents. This has led to the design, synthesis, and antifilarial evaluation of a number of N-substituted quinol-4(1H)-one-3-carboxamide derivatives 4-6. The macrofilaricidal activity of the target compounds was initially evaluated in vivo against Acanthoeilonema viteae by oral administration of 200 mg/kg x 5 days. Among all the synthesized compounds, 13 displayed activity, with the most potent compound (4a) exhibiting 100% macrofilaricidal and 90% microfilaricidal activities. Compound 4e elicited significant macrofilaricidal (80%) response while compound 5c showed 100% sterilization of female worms. Finally, the two most potent macrofilaricidal compounds, namely 4a and 4e, have been screened for their potency against DNA topoisomerase II, and it has been observed that both have the capability to interfere with this enzyme at 10 mumol/mL concentration. The structure- activity relationship (SAR) associated with position-3 and aryl ring substituents is discussed.

A conformational study of formyl and acetyl derivatives of benzofuran provides evidence that in the case of 2- and 7-derivatives the E,Z-conformational mixture is solvent dependent, the Z-form prevailing in solvents with higher polarity.The presence of the same substituents in the 3- and 4-position gives compounds with predominantly Z-conformation and no change is caused by solvents.These results show an interestingly different behaviour by carbonyl derivatives of benzofuran with respect to the same benzothiophene derivatives.The conformational analysis was carried out by the n.m.r. method by employing (1)H and (13)C chemical shifts, long-range proton-proton coupling constants, and lanthanide-induced shifts (LIS) simulation.For the derivatives substituted in position 7, the LIS method is not a suitable approach for the determination of the conformer populations since, in solution, a chelate is formed where bonding of Eu to the oxygen atoms of the carbonyl and of the heterocyclic ring stabilizes the Z-form.A quantitative approach for determining the relative conformer populations of benzofuran-7-carbaldehyde was set up by statistical manipulation of long-range proton-proton coupling constants, proton chemical shifts, and the classical of dielectrics.
