Synthesis of Spiro Compounds Based on Bicyclo[3.3.1]nonane

Organic compounds with bicyclic structure are important because of their stereochemical features and biological activity. The studies of synthesis of spiro compounds bearing bicyclo[3.3.1]nonane framework were based on bicyclo[3.3.1]nonan-2,6-dione and ...

Synthesis of amino- and hydroxyl-substituted bridged bicyclic compounds and their application in asymmetric catalysis

, 2008
In this work, hydroxyl- and amino-substituted bridged bicyclic compounds based on bicyclo[2.2.1]heptane, bicyclo[2.2.2]octane and bicyclo[3.3.1]nonane were synthesized and investigated for use in asymmetric catalysis.

Azasilicon-bridged heterocyclic arylamines: syntheses, structures and photophysical properties

, 2018
The lithium κ1-enamides undergo intermolecular cyclization reactions affording bis-azasilicon-bridged heterocyclic arylamines, which were hydrolysed to the saturated 1,4-diimines, and alternatively proceeded a redox reaction to afford the conjugated 1,4 ...

Heterogenous oxidation of [2.2.1] bridged bicyclic alkenes with KMnO4-CuSO(4 center dot)5H(2)O: An alternative ozonolysis

, 2000
Seven [2.2.1] bridged alkenes were cleaved to the corresponding dialdehyde products by neutral heterogenous oxidation with KMnO4-CuSO4. 5H(2)O. While endo, endo-dimethyl bicyclo[2.2.2]oct-5-ene-2,3-dicarboxylate, [2.2.2] bridged alkene, gave the ...
