Herbicides

The invention provides certain herbicidal thiazolotriazole sulphonamides, processes for their preparation, and compositions containing them, the compounds being of the formula: STR1 where: R1 and R2, which may be the same or different, each represent hydrogen, hydroxy, halo, cyano, substituted or unsubstituted alkyl, alkoxy, alkenyloxy, alkynyloxy, aryl, aralkyl, heteroaryl or carbamoyl, or a group –CORa or –CO2 Ra or where Ra is hydrogen or alkyl; or R1 and R2 together represent an alkylene chain of 3 or 4 carbon atoms; R3 represents a substituted or unsubstituted aryl, heterocyclyl or benzheterocyclyl group; and R4 represents hydrogen, an alkali-metal atom, an ammonium group, a substituted or unsubstituted alkyl, alkenyl, alkynyl, acyl, alkoxycarbonyl or aralkyl group, a heterocyclic group, or a group of the formula: STR2 where R1 and R2 are as defined hereinbefore.

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.17402-83-4, you can also check out more blogs about17402-83-4

Palladium-catalyzed direct C(sp3)-H arylation of indole-3-ones with aryl halides: A novel and efficient method for the synthesis of nucleophilic 2-monoarylated indole-3-ones

A novel and efficient method for the synthesis of nucleophilic 2-monoarylated indole-3-ones via palladium-catalyzed direct C(sp3)-H arylation of indole-3-ones with aryl halides has been developed. Various 2-monoarylated indole-3-ones were readily obtained with yields up to 95%. As a class of important nucleophilic intermediates, 2-monoarylated indole-3-ones can be used for the construction of C2-quaternary indolin-3-one skeletons.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 4923-87-9 is helpful to your research. 4923-87-9

Highly emissive B?N unit containing four-coordinate C,N-Chelated organoboron compound for the detection of fluoride ions

The highly emissive B?N unit containing four-coordinate C,N-chelated organoboron compound, 2 was synthesized. This air and moisture stable compound can be used as a turn-off type fluorescent fluoride (F?) sensor in THF with good selectivity and reversibility. The DFT calculation and the fluorescence quenching titration results showed that the mechanism of the sensing process was based on a competing reaction: the formation of 2-F with the stronger B[sbnd]F bond in an open form took the place of 2 with B?N bond in a closed form when F? was introduced, leading to significant absorption changing and fluorescence quenching.

Synthesis and Intramolecular Azo Coupling of 4-Diazopyrrole-2-carboxylates: Selective Approach to Benzo and Hetero [c]-Fused 6H-Pyrrolo[3,4-c]pyridazine-5-carboxylates

A high yield synthesis of fluorescent benzo, thieno, and furo [c]-fused methyl 7-aryl-6H-pyrrolo[3,4-c]pyridazine-5-carboxylates, including unprecedented heterocyclic skeletons, was performed by the transformation of methyl 4-aminopyrrole-2-carboxylate into the corresponding diazo compound, followed by intramolecular azo coupling under acid conditions onto a nucleophilic aryl or hetaryl group in the 3-position. Azo coupling is completely regioselective and, according to DFT calculations, a kinetically controlled reaction. N-Methylation of 1,3-disubstituted 2H-pyrrolo[3,4-c]cinnolines occurs selectively at N5 under kinetic control, leading exclusively to 5-methyl-5H-pyrrolo[3,4-c]cinnoline derivatives.

Antagonizing STAT3 activation with benzo[b]thiophene 1, 1-dioxide based small molecules

STAT3 is an attractive therapeutic target for cancer therapy. However, due to low potency or poor druggability, none of its inhibitors are clinically available. Herein, a series of aminobenzo[b]thiophene 1, 1-dioxides with good drug-likeness properties were designed, synthesized and evaluated as STAT3 inhibitors. Most of them exhibited higher antitumor activity than the small-molecule STAT3 inhibitor, Stattic. Compound 15 was the most potent and had an IC50range in 0.33?0.75?muM in various cancer cell lines. The overexpressed and IL-6 induced phosphorylation levels of STAT3 were both inhibited by 15 without influencing the phosphorylation levels of the upstream kinases Src and Jak2. 15 also suppressed the expressions of STAT3 downstream gene, Bcl-2. 15 effectively increased the ROS levels of cancer cells, induced cancer cell apoptosis and abolished the colony formation ability of cancer cells without affecting bypass kinase p-Erk. Furthermore, 15 in?vivo induced significant antitumor responses, and exhibited less toxicity than Doxorubicin. Together, this study described a class of new STAT3 inhibitors as antitumor agents.

Sequential palladium-catalysed C- and N-arylation reactions as a practical and general protocol for the synthesis of the first series of oxcarbazepine analogues

The first series of oxcarbazepine analogues, starting from readily-available materials and through a high-yielding five-step sequence based on palladium catalysis, is reported. The so-obtained compounds incorporate not only a variety of substituents in both of?the aryl rings comprising the framework of an oxcarbazepine, but also involve the more challenging palladium-catalysed coupling of a number of heteroaromatic substrates. The addition of small amounts of water in some of the metal-catalysed processes showed a beneficial effect, highly increasing the selectivity of such reactions.
