Reactions of Methyl Acetylenecarboxylate with Heterocyclic Enamines: [2+2] Cycloadditions in Polar and Non-Polar Solvents
(Asian Journal Of Chemistry, 2014)
In this study, enamines of cyclic ketones reacting with methyl acetylenecarboxylate to produce intermadiate cyclobutene adducts have been isolated. Reactions of methyl acetylenecarboxylate with enamines derived from ...
Carbon nanotube-based nanocomposites and their applications
(Taylor & Francis Ltd, 2017)
The purpose of the current review article is to present a compherensive understanding regarding pros and cons of carbon nanotube-related nanocomposites and to find ways in order to improve the performance of nanocomposites ...

Facile synthesis of the azocino[4,3-b]indole framework of strychnopivotine and other Strychnos alkaloids
(Springer, 2016)
A new synthetic route to the 1,5-methanoazocino[4,3-b]indole is described. The aim of the present study is to provide a tetracyclic skeleton for the synthesis of pentacyclic Strychnos alkaloids (tubifolidine and ...
Selective oxidative deoximation with anhydrous Ce(IV) sulfate
(Pergamon-Elsevier Science Ltd, 2015)
Anhydrous Ce(SO4)(2) in chloroform selectively converts oximes into the parent carbonyl compounds in good yields. Hammett correlations helped to indicate a plausible mechanism for the above reaction. The formation of ...
Antioxidant activity of five new phenolic compounds from Cirsium creticum subsp. creticum
(Elsevier Science Bv, 2019)
In this study, five new alkyl catechol derivatives, 1, 2, 3, 4 and 5 were isolated for the first time from Cirsium creticum subsp. creticum L. and their structures were determined by using spectroscopic techniques, including ...
A novel synthesis of octahydropyrido[3,2-c]carbazole framework of aspidospermidine alkaloids and a combined computational, FT-IR, NMR, NBO, NLO, FMO, MEP study of the cis-4a-Ethyl-1(2hydroxyethyl)-2,3,4,4a,5,6,7,11c-octahydro-1H-pyrido[3,2-c] carbazole
(Elsevier, 2018)
In this study, we performed a novel synthesis of the octahydropyrido[3,2-c]carbazole derivative 6 from 1 in five steps with a 34% overall yield. We also developed a unique compound 2 by a cyclization reaction from the ...
A new immobilization procedure for development of an electrochemical immunosensor for parathyroid hormone detection based on gold electrodes modified with 6-mercaptohexanol and silane
(Elsevier, 2015)
Fabrication of a new electrochemical impedance-based biosensor for the analysis of parathyroid hormone (PTH), using self-assembled monolayers (SAMs) of mercaptohexanol and (3-Aminopropyl) triethoxysilane on gold electrodes, ...
Ultrasensitive electrochemical detection of cancer associated biomarker HER3 based on anti-HER3 biosensor
(Elsevier, 2014)
The development of a new impedimetric biosensor for the detection of HER3, based on self-assembled monolayers (SAMs) of 4-aminothiophenol on gold electrodes, is reported. Anti-HER3 was used as a biorecognition element for ...
Review study of electrochemical impedance spectroscopy and equivalent electrical circuits of conducting polymers on carbon surfaces
(Elsevier Science Sa, 2011)
Electrochemical impedance spectroscopy (EIS) is an experimental method for characterizing electrochemical systems. This method measures the impedance of the concerned electrochemical system over a range of frequencies, and ...
