Fluorescence and aggregation behavior of poly(amidoamine) dendrimers peripherally modified with aromatic chromophores: The effect of dendritic architectures

PAMAM dendrimers of the zeroth to fifth generation (G0-5) have been peripherally modified with phenyl, naphthyl, pyrenyl, and dansyl chromophores. Their fluorescence behaviors are strongly affected by the dendritic architectures at different generations.

catena-poly[[tri-n-butyltin]-μ-N-(1-naphthyl)maleamato]

The crystal structure of catena-poly[[tri-n-butyltin]-μ-3- (1-naphthylaminocarbonyl)acrylato-κ2O1: O3], [Sn(C4H9)3-(C14H10 NO3)]n, is composed of polymeric chains wherein the metal center exhibits a distorted trigonal-bipyramidal geometry, with three n-butyl groups defining the trigonal plane [mean Sn-C 2.133 (7) A] and the axial positions being occupied by the carboxylate O atoms of two different N-(1-naphthyl)maleamate ligands with inequivalent Sn-O distances [2.167 (4) and 2.457 (4) A]. The N-(1-naphthyl)-maleamate fragment forms an essentially planar seven-membered ring involving an intramolecular N-H...O hydrogen bond.

The synthesis of (Z)-4-oxo-4-(arylamino)but-2-enoic acids derivatives and determination of their inhibition properties against human carbonic anhydrase I and II isoenzymes

The synthesis of (Z)-4-oxo-4-(arylamino)but-2-enoic acid (4) derivatives containing structural characteristics that can be used for the synthesis of several active molecules, is presented. Some of the butenoic acid derivatives (4a, 4c, 4e, 4i, 4j, 4k) are

DABCO-catalyzed [3+2] cycloaddition reactions of azomethine imines with N-aryl maleimides: Facile access to dinitrogen-fused heterocycles

DABCO-catalyzed [3+2] cycloaddition of azomethine imines with maleimides has been developed. This method could efficiently furnish dinitrogen-fused tetracyclic heterocycles in high levels of regioselectivity and with good yields.

Synthesis and evaluation of hexahydropyrrolo[3,4-d]isoxazole-4,6-diones as anti-stress agents

A series of 2,3-diphenyl-5-(naphthalen-1-yl)-4H-2,3,3a,5,6,6a- hexahydropyrrolo[3,4-d]isoxazole-4,6-dione derivatives were synthesized via 1,3-dipolar cycloaddition of azomethine N-oxides with N-(α-naphthyl) maleimide. The pyrrolo-isoxazole derivatives were assigned cis- and trans- configurations (3-A and 3-B) with respect to proton C3-H on azomethinic carbon on the basis of their 1H NMR. The reaction proceeds through cis- endo addition rule indicating the predominance of cis isomer. The cis- and trans- isomers of a prototype compound 3a i.e., compound 3a-A and compound 3a-B were evaluated for anti-stress activity in immobilization-induced acute stress. Compound 3a-A (5 and 10 mg/kg) and compound 3a-B (10 mg/kg) attenuated immobilization stress-induced behavioral alterations in Swiss albino mice suggesting that pyrrolo-isoxazole may serve as lead molecule for the development of anti-stress agents.

AIBN initiated free radical homopolymerization of N-(1-naphthyl)maleimide and copolymerization with MMA: Synthesis and characterization

Free radical homopolymerization of N-(1-naphthyl)maleimide (NMI) and copolymerization with MMA were performed in THF at 65°C with AIBN as the initiator. Nine copolymer samples were prepared using different feed ratios of comonomers. The prepared polymer sample have been characterized by solubility test, intrinsic viscosity, FT-IR and 1H NMR spectral analysis. The thermal properties have been studied by thermo-gravimetric analysis.

Synthesis and characterization of new compounds containing 1,4-dithiintetracarboxydiimide units

New compounds containing 1,4-dithiintetracarboxydiimide units were synthesized by the disubstitution reaction of N-substituted 2,3- dichloromaleimide with sodium sulflde nonahydrate or thiourea. IR, UV-vis and 1H-NMR spectroscopy, as well as elemental analysis, confirmed their structures. Thermal conversion of 1,4-dithiine ring to thiophene was monitored by differential calorimetry (DSC) and thermogravimetric (TGA) measurements.

Non-hydroxylic clathrate hosts of [4 + 2]π cycloadducts of phencyclone and N-arylmaleimides: Recognition of aromatic guests

A series of non-hydroxylic crystalline host compounds, [4 + 2]π cycloadducts of phencyclone and N-arylmaleimides having a bicyclo[2.2.1]heptene-7-one system, was synthesized and their inclusion behavior investigated. X-Ray crystal analyses of the inclusion compounds of the N-(1-naphthyl) derivative with butan-2-one, the N-(m-tolyl) derivative with p-xylene, together with the guest-free host and the N-(p-tolyl) derivative with m-xylene indicate that the "space" surrounded by the phenanthrene ring, two phenyl rings and bridge carbonyl of the 1,3-diphenyl-1,3-dihydrocyclopenta[l]phenanthren-2-one moiety plays an important role, not only in the formation of inclusion complexes with the aromatic guests but also in host-host interactions. In every case, the N-aryl succinimide assists complex formation with the guests, in which the weak lattice forces due to C-H ... π and C-H ... O interactions are operative. Methyl-substituted benzenes are effectively recognized by the C-H ... π interactions between the guest molecules and the phenanthrene ring of the hosts.

Reactions of cyclic anhydrides with aromatic primary amines: Part 3 - Synthesis of novel 3-(N-arylcarbamoyl)- and 3-(N-naphthylcarbamoyl)carboxylic acids

Some hitherto unreported 3-(N-arylcarbamoyl)propenoic acids 7a-h and 3-(N-naphthylcarbamoyl)propenoic acid 9 have been synthesized in excellent yields, together with some propanoic acid analogues 11a-h and 12 as potential pesticides. Structural assignments of the products are based on elemental analyses and spectral (IR, 1H NMR, mass) data.
