An Efficient Synthesis of Nitriles from Aldoximes in the Presence of Trifluoromethanesulfonic Anhydride in Mild Conditions
(Maik Nauka/Interperiodica/Springer, 2020)
A new and convenient protocol has been proposed for the transformation of aldoximes to nitriles using trifluoromethanesulfonic anhydride and triethylamine. The proposed method allows a range of aldoximes, including aromatic, ...

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 ...
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 ...
Combined supraclavicular and superficial cervical plexus block for clavicle surgery
(Korean Soc Anesthesiologists, 2020)
Background: Clavicle fractures occur in 35% of shoulder girdle fractures. Surgical fixation is preferred, especially in young patients for optimal functional outcomes, while nondisplaced fractures are usually treated ...
Ultrasound-guided serratus plane block combined with intercostal block for a high-risk patient with pericardial tamponade: A case report
(Wolters Kluwer Medknow Publications, 2020)
Anesthetic management of patients with pericardial tamponade is challenging. A 65-year-old man diagnosed with small-cell lung carcinoma and bilateral malignant pleural effusion in the lungs and pericardial effusion was ...
