The Green Method for Regiospecific Ring Opening of Epoxide with Dimercaptoethane
A simple, efficient, and environmentally friendly one-step regiospecefic ring opening of strained epoxides with dimercaptoethane as a nucleophile in nearly saturated aqueous potassium carbonate is reported. The synthesized ...
a new cerium (III) ion selective electrode based on 2,9-dihydroxy-1,10-diphenoxy-4,7 -dithia decane , a novel synthetic ligand
In the present study, a novel electrode based on 2,9-dihydroxy-1,10-diphenoxy-4,7-dithiadecane (DHDPDTD) that is selective to cerium (III) cations was evaluated electrochemically, and a Nerenstian slope (19.3±1mVdecade−1) ...
Competitive Transport of Seven Metal Cations through Bulk Liquid Membrane Using 5,12 di(phenoxymethyl) 1,4 dioxa 7, 10 dithiacyclododecane 2,3 dione as Carrier
The competitive metal ion transport of copper(II), cobalt(II), zinc(II), cadmium(II), silver(I), chromium(III) and lead(II) with a S–O donor compound was examined. Competitive transport experiments involving the metal ...
15-Lipoxygenase inhibitors: A patent review
Introduction: 15-Lipoxygenases (15-LOXes) are a family of iron-containingproteins that have the capability for unsaturated fatty acid peroxidation inanimals and plants. Two types of the enzyme, 15-LOX-1 and 15-LOX-2, ...
Competitive Transport Studies of Seven Metal Cations Through Bulk Liquid Membrane Using 1,4-Dioxa-7,10-dithiacyclododecane-2,3-dione
Competitive permeation of 7 metal ions from an aqueous source phase containing equimolar concentrations of cobalt(II), copper(II), chromium(III), silver(I), cadmium(II), zinc(II) and lead(II) metal cations at pH = 5 into ...
Synthesis of New β,β -Diketodithioethers via Swern Oxidation and Study of Their Hydrazone Formation Rate
The synthesis of β,β -diketodithioethers 4b-j from corresponding β,β -dihydroxydithioethers 3b-j was carried out by a Swern oxidation using DMSO-oxalyl chloride as oxidizing agent. β,β -Dihydroxydithioethers 3b-j were ...
New procedure for the total synthesis of cilostamide
An efficient rout to snthesis a range of N,-R,R-(2-oxo-1,2-dihydroqunolin-6-yloxy)butanamide, specially Cilostamide, from 5-methoxy-2-nitro benzaldehyde with emphasis on the preparation of the carbostryl(2-quinolinone ring ...
Transport of silver ion through bulk liquid membrane using macrocyclic and acyclic ligands as carriers in organic solvents
The bulk liquid membrane transport of silver (I) ion was studied by dibenzopyridino-18-crown-6(DBPY18C6), 4-nitrobenzo-15-crown-5(NB15C5), 2-aminothiaphenol and a new synthesized ligand, 1,4-dioxa-7,10- dithiacyclododeca ...
Design and synthesis of new derivatives of 3-acetylthiocoumarin as 15-lipoxygenase inhibitors
In this research all of the favorite mono prenyloxythiocoumarins were synthesized and their inhibitory potency against SLO were evaluated.
