ABC Triblock Terpolymers with Orthogonally Deprotectable Blocks: Synthesis, Characterization, and Deprotection
(2015)The development and availability of new protecting groups are vital for all branches of synthetic chemistry. Equally vital is the facile and selective removal of these groups, leaving intact other protecting groups which ...

Analysis of volatile organic compounds released from the decay of surrogate human models simulating victims of collapsed buildings by thermal desorption-comprehensive two-dimensional gas chromatography-time of flight mass spectrometry
(2015)Field experiments were devised to mimic the entrapment conditions under the rubble of collapsed buildings aiming to investigate the evolution of volatile organic compounds (VOCs) during the early dead body decomposition ...

Analytical separations in open-tubular capillary electrochromatography
(2003)This review represents a summary of recent progress in open-tubular capillary electro-chromatography (OT-CEC) for chiral and achiral separations. The OT-CEC approach is an alternative to packed-CEC that could eliminate the ...

Analytical separations using molecular micelles in open-tubular capillary electrochromatography
(2002)Open-tubular capillary electrochromatography (OT-CEC) is an alternative approach to conventional CEC. The primary advantage of OT-CEC is the elimination of problems associated with frits and silica particles in conventional ...

Effect of intravenous nitroglycerin on lipid peroxidation after thrombolytic therapy for acute myocardial infarction
(1998)Free oxygen radicals are produced after coronary artery occlusion and reperfusion. Polyunsaturated fatty acids are oxidized by free radicals to lipid peroxides. Measurements of plasma malondialdehyde (MDA) formed by the ...

Remote functionalization of C60 with enantiomerically pure cyclo-[2]-malonate tethers bearing C12 and C14 spacers: Synthetic access to bisadducts of C60 with the inherently chiral trans-3 addition pattern
(2013)In this Article, we describe the synthesis of two optically pure diols bearing a 1,2-diol moiety masked as an isopropylidene acetal group and long alkyl chains comprised of 12 and 14 carbon atoms, respectively. The synthetic ...
