New heteroaromatic azo compounds based on pyridine, isoxazole, and benzothiazole for efficient and highly selective amidation and mono-N-benzylation of amines under Mitsunobu conditions

4,4?-Azopyridine (2c) is used in conjunction with triphenylphosphine for the efficient conversion of carboxylic acids into amides via Mitsunobu reaction with primary and secondary aliphatic and aromatic amines. The highly selective amidation of only primary aromatic amines with new heterogeneous azo compounds based on benzothiazole 2d and isoxazole 2e is also described. These azo compounds 2c-2e can also be applied for selective mono-N-benzylation of primary aromatic amines. The solid side product heteroaromatic hydrazines obtained under the developed Mitsunobu conditions are easily separated by simple filtration and can be reoxidized to azo compounds for further use.

Palladium-Catalyzed Asymmetric Ring Opening Reaction of Azabenzonorbornadienes with Aromatic Amines

A palladium/(R)-Binap catalyst for asymmetric ring opening reaction of azabenzonorbornadienes with amines was developed that afforded the corresponding substituted dihydronaphthalenes in good yields (up to 97%) with excellent enantioselectivities (up to >99% ee). To the best of our knowledge, this represents the first palladium-catalyzed asymmetric ring opening reaction of azabenzonorbornadienes with heteronucleophiles.

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.

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.
