Selective mono-N-methylation of aniline substrates on Cu1-xZnxFe2O4

Selective mono-N-methylation of substituted anilines (o-, m- and p-toluidines, 2,6-xylidine, p-anisidine and p-aminoacetophenone) was carried out with methanol as methylating agent under vapor phase reaction conditions on Cu1-xZnxFe2O4 systems. The catalytic reactions with each aniline substrate were carried out at optimum reaction conditions (MeOH:anilines:water = 3:1:1, space velocity = 3.58 h-1) between 543 and 603 K. The presence of a ring-directing group did not have any significant influence on the N-methylaniline(s) selectivity, which remains very high; the same initial conversion/yield was observed for at least 11 h. Electronic effects due to different groups in the above aniline substrates influence the reactivity of the substrates in terms of conversion and yield. Toluidine reactivity varies with respect to the position (ortho, meta and para) of the methyl group on the phenyl ring. Para-substituted anilines (p-toluidine and p-anisidine) exhibit comparable catalytic activity, while p-aminoacetophenone shows higher conversion. The perpendicular orientation of toluidine substrates on catalyst surfaces influences the conversion and N-methyltoluidine yield. Increased crowding at ortho-position and hence steric hindrance (aniline > o-toluidine > 2,6-xylidine) restrict the substrates interaction with the catalyst surface, and 2,6-xylidine shows no reactivity. The best catalytic activity observed with Cu0.5Zn0.5Fe2O4 was due to a heterogeneous distribution of metal ions on the surface with Zn serving as active spacer group as well as methyl species source.

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 33282-15-4 is helpful to your research. Synthetic Route of 33282-15-4

Highly Ligand Efficient and Selective N-2-(Thioethyl)picolinamide Histone Deacetylase Inhibitors Inspired by the Natural Product PsammaplinA

Novel picolinamide-based histone deacetylase (HDAC) inhibitors were developed, drawing inspiration from the natural product psammaplinA. We found that the HDAC potency and isoform selectivity provided by the oxime unit of psammaplinA could be reproduced by using carefully chosen heterocyclic frameworks. The resulting (hetero)aromatic amide based compounds displayed very high potency and isoform selectivity among the HDAC family, in addition to excellent ligand efficiency relative to previously reported HDAC inhibitors. In particular, the high HDAC1 isoform selectivity provided by the chloropyridine motif represents a valuable design criterion for the development of new lead compounds and chemical probes that target HDAC1.

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.Computed Properties of C5H5NO3, you can also check out more blogs about3405-77-4

Dirhodium-catalyzed C-H arene amination using hydroxylamines

Primary and N-alkyl arylamine motifs are key functional groups in pharmaceuticals, agrochemicals, and functional materials, as well as in bioactive natural products. However, there is a dearth of generally applicablemethods for the direct replacement of aryl hydrogens with NH2/NH(alkyl) moieties. Here, we present a mild dirhodium-catalyzed C-H amination for conversion of structurally diverse monocyclic and fused aromatics to the corresponding primary and N-alkyl arylamines using NH2/NH(alkyl)-O-(sulfonyl)hydroxylamines as aminating agents; the relatively weak RSO2O-N bond functions as an internal oxidant. The methodology is operationally simple, scalable, and fast at or below ambient temperature, furnishing arylamines in moderate-to-good yields and with good regioselectivity. It can be readily extended to the synthesis of fused N-heterocycles.

Novel [1,2,4] triazol [4,3-a] pyridine derivatives as potential selective c-met inhibitors with improved pharmacokinetic properties

Aims: Total twenty-nine [1,2,4]triazolo[4,3-a]pyrazine derivatives were designed and synthesized. Method: The target compounds, especially 4aa, showed potent activity to inhibit c-Met both in an enzyme assay and a cellular assay. The comprehensive screening for the inhibition of 60 different kinases revealed that 4aa could selectively inhibit c-Met while had no effect on other kinases, indicating 4aa is an excellent c-Met selective inhibitor. Result: The flow cytometry studies found that 4aa had a similar behavior to the positive control SGX-523 in terms of causing the tumor cell apoptosis and blocking cell-cycle progression. More importantly, 4aa showed much better pharmacokinetic properties than SGX-523. Altogether, the findings suggested the target compounds may be potential anti-tumor drug candidates.

Discovery of N-methyl-4-(4-methoxyanilino)quinazolines as potent apoptosis inducers. Structure-activity relationship of the quinazoline ring

As a continuation of our efforts to discover and develop apoptosis inducing N-methyl-4-(4-methoxyanilino)quinazolines as novel anticancer agents, we explored substitution at the 5-, 6-, 7-positions of the quinazoline and replacement of the quinazoline by other nitrogen-containing heterocycles. A small group at the 5-position was found to be well tolerated. At the 6-position a small group like an amino was preferred. Substitution at the 7-position was tolerated much less than at the 6-position. Replacing the carbon at the 8-position or both the 5- and 8-positions with nitrogen led to about 10-fold reductions in potency. Replacement of the quinazoline ring with a quinoline, a benzo[d][1,2,3]triazine, or an isoquinoline ring showed that the nitrogen at the 1-position is important for activity, while the carbon at the 2-position can be replaced by a nitrogen and the nitrogen at the 3-position can be replaced by a carbon. Through the SAR study, several 5- or 6-substituted analogs, such as 2a and 2c, were found to have potencies approaching that of lead compound N-(4-methoxyphenyl)-N,2-dimethylquinazolin-4-amine (1g, EP128495, MPC-6827, Azixa).

A Tandem Ring Opening/Closure Reaction in A BF3-Mediated Rearrangement of Spirooxindoles

Treatment of the readily accessible spiro-cyclohexadienones from the PhI(OCOCF3)2-mediated spiro-cyclization of N-substituted benzanilides, with BF3?Et2O initiates a tandem ring opening/closure reaction leading to the formation of the biologically interesting 8-hydroxy-phenanthridin-6(5H)-one compounds. This unique rearrangement pattern involves the ?migration? of the electron-deficient N-methyl carbamoyl moiety rather than the electron-rich aryl group as observed and reported previously in all other similar transformations.
