A thermal study of some Schiff bases derivative of α-napthylamine

Thermal analyses of some Schiff bases, derivative of α-napthylamine, were performed by the DSC, TG and DTA techniques. The thermograms were used to determine various kinetic parameters, such as the order of degradation (n), energy of activation (E), frequ

Analgesic, anti-inflammatory activity and docking study of 2-(substituted phenyl)-3-(naphthalen-1-yl)thiazolidin-4-ones

A potential analgesic and anti-inflammatory activities have been reported in 4-thiazolidinone analogs as well as some drugs bearing naphthyl moiety such as naproxen. Thus a reported series of 2-(substituted phenyl)-3-(naphthalen-1-yl)thiazolidin-4-ones (T

Preparation of the library of fluorescent aromatic aminophosphonate phenyl and benzyl esters

Classical hydrophosphonylation of Schiff bases have been used for the preparation of library of diphenyl and dibenzyl aromatic aminomethylphosphonates N-substituted with aromatic moieties. The reaction, although being capricious provided the desired products in satisfactory yields. When using harsh reaction conditions conversion of diphenyl esters into monophenyl ones was observed. On the other hand, the use of more delicate conditions resulted in lack of hydrophosphonylation. The fluorescence studies revealed that the obtained library could be used for the construction of diagnostic microarrays.

Synthesis of optically active 1,2,3-trisubstituted azetidines employing an organocatalytic approach with L-proline

A concise organocatalytic approach towards optically active 1,2,3-trisubstituted azetidines, including a study of the scope and limitations of the synthetic sequence, is reported. The synthesis comprises the one-pot L-proline promoted three-component reac

Synthesis and antibacterial activities of some schiff bases

Schiff bases p-hydroxybenzylidene-2-carboxyaniline, p-nitrobenzylidene-2- carboxyaniline, p-(N, N-dimethyl)aminobenzylidene-2-carboxyaniline, N-(4-hydroxybezylidene)-benzene-1,2-diamine, N-(4-nitrobezylidene)benzene-1,2- diamine,N-(4-(N, N-dimethylaminobezylidene)benzene-1,2-diamine, N-(4-(N,Ndimethylamino) benzylidene)naphthalen-1-amine,N-(4-nitrobenzylidene) naphthalen-1-amine,N-(4-chlorobenzylidene)naphthalen-1-amine,sodium-4-(4-(N, N-dimethyl amino)benzylideneamino)naphthalene-1-sulfonate,sodium -4-(4-nitrobenzylideneamino) naphthalene-1-sulfonate and sodium-4-(4- chlorobenzylideneamino) naphthalene-1-sulfonate obtained by condensation of aniline and naphthylamine derivatives with some aromatic aldehydes were characterized by physical and spectral methods. The biological activity of these products were as antibacterial agents against three species of human pathogenic bacteria such as Escherichia coli, Staphylococcus aureus and Klebsiella sp. Nearly 50% of these compounds showed reasonable activity against the bacterial species investigated and we found that the antibacterial activity is dependent on the molecular structure of the compounds.

Quantitative solid-solid synthesis of azomethines

Twenty preparatively useful azomethines have been quantitatively (100% yield at 100% conversion) obtained as hydrates by grinding together solid anilines with solid benzaldehydes without passing through liquid phases. Unlike (acid catalyzed) azomethine syntheses in solution, the solid-solid condensations proceed 'waste-free'. The solid-state mechanisms have been elucidated by atomic force microscopy (AFM) and in part by scanning near-field optical microscopy (SNOM) in three cases. The results indicate long distance migration of the aldehydes into the lattice of the aniline derivatives. Stumpy protrusions are formed at the direct points of contact but also distance sublimation (100 nm range) is succesful in the case of p-chlorobenzaldehyde and p-nitroaniline. Long-range flow of 4-hydroxybenzaldehyde molecules on its (010)-face into contracting crystals of p-toluidine or p-anisidine occurs along two different cleavage planes. Steep hills and valleys are left behind. The molecular migrations through the sites of contact are interpreted in terms of crystals packing. The ease of these solid-solid condensation reactions relies on the crystal packing.

Cycloaddition of (N-Alkyl-N-phenylamino)ketene with Imines

(N-Alkyl-N-phenylamino)ketenes were prepared in the presence of various imines, and a cycloaddition reaction occurred to yield 3-(N-alkyl-N-phenylamino)-2-azetidinones.The size and electronic nature of the imine substituents were varied in order to probe those factors that influence the stereochemistry of the cycloaddition.The stereochemistry of the 2-azetidinone was determined by the substitution pattern of the imines.In general, the stereochemistry of the 2-azetidinone products are significantly influenced by the bulk of the N substituent on the imine.These results are discussed in terms of a two-step zwitterionic intermediate.
