Theory of Three-Electron Bond in the Four Works with Brief
Journal Title: Organic Chemistry: Current Research - Year 2017, Vol 6, Issue 2
Abstract
Using the concept of three-electron bond we can represent the actual electron structure of benzene and other molecules, explain specificity of the aromatic bond and calculate the delocalization energy. Gives theoretical justification and experimental confirmation of existence of the three-electron bond. It was shown, that functional relation y=a+b/x+c/ x2 fully describes dependence of energy and multiplicity of chemical bond from bond distance

Stereoselective Total Synthesis of Proposed Structure of Stagonolide D
The stereoselective total synthesis of the proposed structure of naturally occurring nonenolide stagonolide D has been achieved using D-mannitol as the starting material. The latter has been utilized for the preparation...
Synthesis, Characterization and In Vitro Antitumor Evaluation of New Pyrazolo[3,4-d]Pyrimidine Derivatives
A new series of 3-(methylthio)-1-phenyl-1H-pyrazolo[3,4-d]pyrimidine derivatives was synthesized. The antitumor activity of this series against human breast adenocarcinoma cell line MCF7 was evaluated. Out of twenty new...
Enantioselective Michael Addition of Diethyl Malonate on Substituted Chalcone Catalysed by Nickel-Sparteine Complex
A series of transition metal with Sparteine a novel chiral catalyst was facilely synthesized, all of which contain a chiral Sparteine unit as a bidentate ligand. These bidentate chiral auxiliaries were found to be an eff...

Generation of α-Linked Oligosaccharide Libraries by Random Glycosylation on Unprotected Acceptors
Background: The GlcNAc related disaccharides were reported to show inhibitory activity on breast tumor cells (MDAMB- 231). However, synthesis of disaccharides is lengthy, laborious and time consuming, and it is necessary...
