A New Approach to the Total Synthesis of 20-Deethyltubifolidine and an Entry to the Azocino[4,3-b]indoles
(Taylor & Francis Inc, 2020)
[No Abstract Available]
A Facile and Convenient Synthesis of (+/-)-Dasycarpidone
(Springer, 2020)
An efficient new pathway for (+/-)-dasycarpidone has been synthesized. The most important step in the synthesis of (+/-)-dasycarpidone is the intramolecular cyclization of the azocino[4,3-b]indole skeleton, which is ...
An efficient studies on C-2 cyanomethylation of the indole synthesis: the electronic and spectroscopic characterization (FT-IR, NMR, UV-Vis), antioxidant activity, and theoretical calculations
(Elsevier, 2022)
The direct cynamethylation with the development of catalyzed methodologies directed to 2-(cyanomethyl)indoles was reported by using tetrafluoro-1,4-benzoquinone (TFB) as the catalyst and it was synthesized in one step ...
Forced Degradation Studies of Nateglinide by the First-Order Derivative Spectrophotometric Method and the Density Functional Theory of the Nateglinide Molecule
(Springer, 2022)
Nateglinide (NAT) is an oral antihyperglycemic agent used for the treatment of noninsulin-dependent diabetes mellitus. We evaluated the NAT stability under various forced degradation tests (acidic, basic) and predicted the ...
Cyanomethylation of 2,3,4,9-tetrahydro-1H-carbazol-1-one based on using two different reagents: Antioxidant activity and DFT studies
(Elsevier, 2022)
C-2 and C-6 monoalkyl nitrile substituted reactant (1), which constitute the tricyclic framework of carbazole derivatives along with the substructure of the Strychnos alkaloids family, have been synthesized by using different ...
New route for synthesis of 2-(2,2-dimethoxyethyl)-1,2,3,4,5,6-hexahydro-1,5-methanoazocino[4,3-b] indole and DFT investigation
(Elsevier Sci Ltd, 2020)
Development of efficient sequences for the synthesis of the title compound (2-(2,2-dimethoxyethyl)-1,2,3,4,5,6-hexahydro-1,5-methanoazocino[4,3-b]indole) (7) was described. The title compound was synthesized through several ...
The electronic and spectroscopic investigation of ( +/- )- Dasycarpidone
(Elsevier, 2020)
(+/-)-Dasycarpidone ((1R,5S)-12-ethyl-2-methyl-1,2,3,4,5,7-hexahydro-6H-1,5-methanoazocino[4,3-b]indol-6one) was investigated by using the quantum chemical calculations. All DFT-based analyses were performed by B3LYP, ...
Synthesis, characterization, UV-Vis absorption and cholinesterase inhibition properties of bis-indolyl imine ligand systems
(Elsevier, 2020)
A number of bis-indolyl imine helical structures has successfully been synthesized employing Schiff base reaction conditions starting from 4,6-dimethoxy-2,3-diphenylindole with different o-phenyl diamines as pi-spacer ...
Electrochemical Characteristics of a Novel Pyridinium Salt as a Candidate Drug Molecule and Its Interaction with DNA
(Wiley-V C H Verlag Gmbh, 2020)
In this article, for the first time, the electrochemical properties of a novel pyridine derivative, 4-(2-(2-hydroxybenzylidene) hydrazinyl)-1-(3-phenylpropyl) pyridinium bromide (abbreviated as 4-Pyri), and its interaction ...
Synthesis of Methylene Bridged Bis-pyrrolo[3,2-c]carbazoles via an Unusual Vilsmeier-Haack Product of N-Ethylcarbazole
(Taylor & Francis Ltd, 2020)
The unexpected result for the formylation of N-ethylcarbazole under the Vilsmeier-Haack conditions (POCl3/DMF) led to the synthesis of novel methylene bridged bis-pyrrolo[3,2-c]carbazoles via Hemetsberger indole synthesis ...
