A modular phosphate tether-mediated divergent strategy to complex polyols
(Beilstein-Institut, 2014-10-07)An efficient and divergent synthesis of polyol subunits utilizing a phosphate tether-mediated, one-pot, sequential RCM/CM/reduction process is reported. A modular, 3-component coupling strategy has been developed, in which, ... -
A potassium crown ether complex with dichloroaurate(I)
(International Union of Crystallography, 2003-01-17)The title compound, (1,4,7,10,13,16-hexaoxacyclooctane)potassium dichloroaurate(I), [K(C12H24O6)][AuCl2], consists of potassium ion encapsulated by the 18-membered crown ether 1,4,7,10,13,16-hexaoxacyclooctane and ... -
Photorelease of phosphates: Mild methods for protecting phosphate derivatives
(Beilstein J Org Chem, 2014-08-29)We have developed a new photoremovable protecting group for caging phosphates in the near UV. Diethyl 2-(4-hydroxy-1-naphthyl)-2-oxoethyl phosphate (14a) quantitatively releases diethyl phosphate upon irradiation in aq ... -

Rational design of cyclopropane-based chiral PHOX ligands for intermolecular asymmetric Heck reaction
(Beilstein-Institut, 2014-07-07)A novel class of chiral phosphanyl-oxazoline (PHOX) ligands with a conformationally rigid cyclopropyl backbone was synthesized and tested in the intermolecular asymmetric Heck reaction. Mechanistic modelling and crystallographic ... -
Charge-Transfer Induced Magnetic Field Effects of Nano-Carbon Heterojunctions
(Nature Publishing Group, 2014-08-22)Room temperature magnetic field effects have not been definitively observed in either single-walled carbon nanotubes (SWCNTs) or C60 under a small magnetic field due to their weak hyperfine interaction and slight difference ... -
Lifting the Mask: Identification of New Small Molecule Inhibitors of Uropathogenic Escherichia coli Group 2 Capsule Biogenesis
(Public Library of Science, 2014-07-01)Uropathogenic Escherichia coli (UPEC) is the leading cause of community-acquired urinary tract infections (UTIs), with over 100 million UTIs occurring annually throughout the world. Increasing antimicrobial resistance among ... -

The Transport Number of Silver Fluoride Using a Pulsating Current
(University of Kansas, 1914-06-05)It was thought probable that the transport number of an electrolyte is different when using a pulsating current, than when using a steady current, on account of the difference of inertia's of different ions, due to ... -

Solid State and Solution Characterization of Copper and Cobalt Complexes with Amide and Thioamide Ligands
(University of Kansas, 2012-12-31)Low molecular weight ligands have been extremely useful for mimicking active intermediates. While often times these low molecular weight compounds are synthesized with ligands that do not always fully mirror the active ... -
Synthesis of Densely Functionalized Cyclopropanes via Diastereoselective Nucleophilic Additions to in Situ Generated Cyclopropenes
(University of Kansas, 2013-12-31)This thesis is concerned with the development and application of methods for the diastereoselective synthesis of substituted cyclopropanes. The methodology described in this dissertation is based on the addition of ... -
Discovery of a Novel Compound with Anti-Venezuelan Equine Encephalitis Virus Activity That Targets the Nonstructural Protein 2
(Public Library of Science, 2014-06-26)Abstract Alphaviruses present serious health threats as emerging and re-emerging viruses. Venezuelan equine encephalitis virus (VEEV), a New World alphavirus, can cause encephalitis in humans and horses, but there are no ... -
