Synthesis of fluorinated alkoxyamines and alkoxyamine-initiated nitroxide-mediated precipitation polymerizations of styrene in supercritical carbon dioxide
(Royal Society of Chemistry, 2014-06-20)
TIPNO (2,2,5-trimethyl-4-phenyl-3-azahexane-3-nitroxide)-alkoxyamine was found to give reasonably controlled/living nitroxide-mediated (NMP) precipitation polymerizations of styrene in supercritical carbon dioxide (scCO(2)). ...
Chain transfer to solvent in the radical polymerization of structurally diverse acrylamide monomers using straight-chain and branched alcohols as solvents
(Royal Society of Chemistry, 2014-01-02)
Chain transfer to solvent in conventional radical polymerizations of N-tert-butylacrylamide (TBAM) and N-(2-morpholin-4-ylethyl) acrylamide (MEA) in a range of alcohol solvents is investigated. Mayo analysis of polymerization ...
An experimental and modeling study of propene oxidation. Part 1: Speciation measurements in jet-stirred and flow reactors
(Elsevier ScienceDirect, 2014-06-20)
Propene is a significant component of Liquefied Petroleum Gas (LPG) and an intermediate in the combustion of higher order hydrocarbons. To better understand the combustion characteristics of propene, this study and its ...
Nerve growth factor-mediated inhibition of apoptosis post-caspase activation is due to removal of active caspase-3 in a lysosome-dependent manner
(Nature Publishing Group, 2014-05-01)
Nerve growth factor (NGF) is well characterised as an important pro-survival factor in neuronal cells that can inhibit apoptotic cell death upstream of mitochondrial outer membrane permeabilisation. Here we addressed the ...
Tandem reactions via Barton Esters with intermolecular addition and vinyl radical substitution onto indole
(American Chemical Society, 2014-05-16)
A one-pot initiator-free Barton ester decomposition with tandem radical addition onto alkyl propiolates or phenylacetylene with aromatic substitution of the resultant vinyl radical allows convenient access to new 9-substituted ...
On exceptional vertex operator (Super) algebras
(Springer, 2014-10-01)
We consider exceptional vertex operator algebras and vertex operator superalgebras with the property that particular Casimir vectors constructed from the primary vectors of lowest conformal weight are Virasoro descendents ...
Using rapid compression machines for chemical kinetics studies
(Elsevier, 2014-04-26)
Rapid compression machines (RCMs) are used to simulate a single compression stroke of an internal combustion engine without some of the complicated swirl bowl geometry, cycle-to-cycle variation, residual gas, and other ...
Synthesis of iminosugar derivatives presenting naphthyl and alkyl amine interacting groups and binding to somatostatin receptors
(Royal Society of Chemistry, 2014-03-20)
The synthesis of 1-deoxynojirimycin (DNJ) derivatives presenting a 2-naphthylmethyl and an alkyl amino side chain from L-sorbose is described. The synthetic derivatives were tested for their ability to inhibit the binding ...
Synthesis of migrastatin and its macroketone analogue and in vivo FRAP analysis of the macroketone on E-Cadherin dynamics
(Wiley-VCH Verlag, 2014-06-11)
An efficient and scalable synthesis of a key acyclic intermediate used for the preparation of migrastatin and its macroketone analogue is described; Brown alkoxyallylation is the key step for this synthesis. The macroketone ...
Synthesis of α-galactosyl ceramide analogues with an α-triazole at the anomeric carbon
(Elsevier, 2014-03-16)
The synthesis of 1,2,3-triazole containing analogues of a-GalCer and galacturonic acid containing Sphingomonous cell wall antigens is described. Anomerisation was used to provide the required cc-glycosyl azide precursor. ...
