A series of new compounds (1–12) containing 1,5-diaza-fluorenone, 1,10-phenanthroline-5,6-dione, ferrocene-1,1ʹ-dione, anthracene-9-carbaldehyde have been synthesized and optimized. The nanomaterials were also developed successfully. The binding properties were evaluated for biologically important anions (F−, Cl−, Br−, I−, AcO−, and H2PO4−) by theoretical investigation, UV-vis, and fluorescence...

Quinones such as 1,4-naphthoquinones are abundant in nature and naphthoquinone based natural products are known to possess anticancer activity. This pharmacophore is known to convey anticancer activity to some drugs such as streptonigrin, mitomycin A, etc. We synthesized and characterized different classes of naphthoquinone derivatives including bis naphthoquinone, 2-arylaminonaphthoquinone, be...

This study reports the synthesis of a series of 2-aroylquinoline-5,8-diones (11-23) on the basis of scaffold hopping. The presence of a methoxy group at C6 assists the highly regioselective incorporation with various amines, and simplifies the structural identification process. Among the synthetic compounds, 6-dimethylamino-2-(3,4,5-trimethoxybenzoyl)-quinoline-5,8-dione (12) and 7-pyrrolidin-1...

The title compound {systematic name: poly[[aqua-lithium]-μ-3,3,8,8-tetra-methyl-1,4,6,9-tetra-oxa-5λ(4)-borataspiro-[4.4]nonane-2,7-dione]}, [Li(C(8)H(12)BO(6))(H(2)O)](n) (LiBMLB), forms a 12-membered macrocycle, which lies across a crystallographic inversion center. The lithium cations are pseudo-tetra-hedrally coordinated by three methyl-lactate ligands and a water mol-ecule. The asymmetric ...

Aminoanthraquinones were successfully synthesized via two reaction steps. 1,4-Dihydroxyanthraquinone (1) was first subjected to methylation, reduction and acylation to give an excellent yield of anthracene-1,4-dione (3), 1,4-dimethoxyanthracene-9,10-dione (5) and 9,10-dioxo-9,10-dihydroanthracene-1,4-diyl diacetate (7). Treatment of 1, 3, 5 and 7 with BuNH2 in the presence of PhI(OAc)2 as catal...

The repeated introduction of an a-dione unit and its reaction with an arene-1,2-diamine allows the stepwise annulation of all four pyrrolic rings of a porphyrin, as is demonstrated by the synthesis of a trisquinoxalinoporphyrin, a tetrakisquinoxalinoporphyrin and the more elaborated bisporphyrin.

Abstract: Background: Diabetes mellitus, a lifestyle related global health crisis has rapidly engulfed the entire world. In past, various thiazolidinedione derivatives have been successfully developed for management of diabetes. Materials and Methods: Herein, we report synthesis, characterization (1H-NMR, 13C-NMR mass spectroscopy methods) novel aryl sulfonyloxy-5-arylidene thiazolidine-2,4-dio...

This study includes synthesis and characterization of new derivatives 3-(2-(6-oxo-1,3-thiazinan-3-yl)-R)-1,3-oxazepane-4,7-dione N-Bromo amines 1,3-oxazepane-4,7-dione derivatives. Schiff's bases reactions through one step process in inert solvents. Some employing [1- 4]; addition, synthesized by the reaction different with (Salicylaldehyde) absolute ethanol under reflux. Heterocyclic rings pre...
