In 1974, an environmental water-testing laboratory was established by the Department of Physical Science at Southern Utah University. Since its inception, the Water Lab has involved students in every facet of its operation while maintaining state certification/National Environmental Laboratory Accretidation Program (NELAP) certification. However, relying on student workers means that the Water Lab suffers constant turnover, which makes both training and maintaining state certification difficult. The SUU Water Lab solves this problem by relying on peer mentorship. In this chapter, we present the challenges of constant turnover and discuss how we maintain state certification with student workers, as well as the overall benefits of the peer mentoring process to students.
The major ions of Coal Creek near Cedar City, in southwest Utah, were measured to determine if there were any differences in ion concentrations in July of 2014 as compared with spring measurements of 2012 and 2013. Past analyses have shown higher ion concentrations in lower regions of Coal Creek despite the apparent lack of water input. This research is aimed to better characterize these abrupt increases in concentration and determine if these trends varied when samples were acquired in the summer vs. in the spring when sample acquisition has occurred in the past. Environmental water samples were collected at evenly spaced locations in Coal Creek from State Route 14 Mile Marker 7 westward to where the creek intersects with Main Street in Cedar City. Ion concentrations were determined in water samples collected every other day for 3 consecutive weeks using Ion Chromatography (IC) and Atomic Absorption Spectroscopy (AA). The spatially intensive sampling revealed two previously unknown low volume springs that are highly concentrated in the major ions and discharge into the creek. Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) was used to characterize trace metal concentrations within the water tributaries, in addition to IC to determine bulk anion content in the creek. The high ion concentrations of springs correlated well with known geologic features near the creek, such as faulted gypsum layers creating springs as well as evaporate deposits, both of which explain the doubling of ion concentrations seen in the examined section of Coal Creek.
Sequential science courses that cover multiple semesters, with each course serving as a prerequisite for subsequent courses, create a unique challenge for student engagement and success, as students are expected not only to engage with the new material, but also to quickly connect it with previously learned material.
Macrocycles comprise a large group of heterocyclic organic compounds that can bind cationic, anionic, or neutral substrates by entrapment within the cavity created by the macrocyclic structure. The selectivity of the macrocycle for certain chemical species is a function of many parameters, an important one being the match between substrate size and macrocycle cavity size. These host-guest systems may be exploited to yield valuable insights into molecular recognition, separation science, and biomimetics. Macrocyclic compounds constitute the building blocks for constructing supramolecular systems for the study of noncovalent molecular interactions.
Coal Creek is a small, perennial stream, fed by mountain runoff, which is located in the Coal Creek Drainage Basin in the Cedar City, Utah area. The increasing urbanization of the Cedar City area raises concern about the water quality in the basin. This study focuses on characterizing pollutants from non-point sources and their impact on the water quality of Coal Creek and the organisms living within it. Analytes of interest include: common anions, mineral metals, pH, turbidity, conductivity and pesticides. The determination of pollutant concentrations in runoff and affected surface water will be beneficial to understand basic sources of non-point source pollution. It is hoped that this study will help to better understand the effects of population growth and urbanization on the water quality of Coal Creek and the organisms living within it.
Asymmetric dihydroxylation of 1,1-disubstituted and 1,3-disubstituted allenes can be used to synthesize chiral α-hydroxy ketones. We have also obtained α,α′-dihydroxy ketones with high enantioselectivity from 1,3-disubstituted allenes. Low conversion of the dihydroxylation of chiral allenes can be used as a kinetic resolution of sterically hindered allenes.
We have used asymmetric dihydroxylation (AD) of allenes in order to synthesize chiral α-hydroxy ketones. This methodology has been applied to several aryl-substituted allenes. We have found that electron donating groups on the aromatic ring increase the efficiency of the reaction.
Three novel enantiomerically pure chiral pyridino-18-crown-6 ligands [(S,S)-7, (S,S)-8 and (R,R)-9] containing a linker with a terminal carboxyl function were prepared. One of them [(R,R)-9] containing two tert-butyl groups at the stereogenic centers was covalently attached to silica gel by an amide bond using 3-aminopropyltrimethoxysilane. The resulting chiral stationary phase [(R,R)-11] separated the enantiomers of racemic α-(1-naphthyl)ethylammonium perchlorate and 1-phenylethylammonium perchlorate by high-performance liquid chromatography.
Five new proton-ionizable macrocyclic ligands containing a pyrimidone-subcyclic unit, 6–10, were prepared from the previously prepared pyrimidinocrown ethers 1–5 (see Figure 1 and Scheme 1). One of the new proton-ionizable crown ethers is chiral. The proton-ionizable pyrimidonocrown ethers were prepared in high yields by treating the appropriate methoxy-substituted pyrimidinocrown with 5 M sodium hydroxide in a 50% alcohol-water mixture. Complexation properties of four of the pyrimidine-derived macrocycles were studied by various nmr techniques. Pyrimidono-18-crown-6 (9) forms a strong complex with benzylammonium perchlorate and also forms a complex with benzylamine. (S, S)-Dimethyl-substituted pyrimidino- and pyrimidono-18-crown-6 ligands 4 and 9 form stronger complexes with the (R)-form of α-(1-naphthyl)ethylammonium perchlorate than with the (S)-form. (S, S)-Dimethyl-substituted pyrimidono-18-crown-6 (9) also forms a stronger complex with (R)-α-(1-naphthyl)ethylamine than with the (S)-form. The crystal structure for compound 7 is reported.
Pyrimidino-crown ethers were prepared in 30-50% yields by reactingthe ditosylate derivative of the appropriate oligoethylene glycol with4-methoxy-5-methyl-2,6-pyrimidinedimethanol under basic conditions. A newmacrocyclic ligand containing a proton-ionizable pyrimidone subcyclic unitwas prepared in 88% yield by treating the appropriatepyrimidino-crown ether with 5 M NaOH in 50% (v/v) aqueous methanol.Preliminary complexation properties of some of these new compounds werestudied using various NMR spectral techniques. Good enantiomeric recognitionwas exhibited by a chiral pyrimidino-crown ether for the enantiomers of1-(α-naphthyl)ethylammonium perchlorate.
Traditionally, heterocycles are three- to eight- or nine-membered rings that contain one or more noncarbon "heteroatoms." Many, if not most, of the known heterocycles are aromatic compounds in which the noncarbon atoms contribute electrons to meet Huckel rule requirements. The crown ether situation contrasts with that of traditional heterocycles.
Chiral pyridino-18-crown-6 ligands interact with chiral primary organic ammonium salts by hydrogen bonding from the ammonium cation to the pyridino nitrogen and two alternate ring oxygen atoms. Enantiomeric recognition in these interactions are caused by the steric bulk of the substituents at chiral macrocycle ring positions. Recognition is best for the interaction of chiral pyridino-18-crown-6 hosts with the enantiomers of α-(l-naphthylethyl)ammonium perchlorate (NapEtHClO4) over (α-phenylethyl)ammonium perchlorate (PhEtHC104) possibly because of a greater π-π overlap between the naphthalene ring of the guest and pyridine ring of the host. Solvents play an important role in the degree of recognition. A binary solvent composed of 7/3 C2H4Cl2/CH3OH (v/v) gave an enhanced degree of recognition. A new chiral pyrimidino-18-crown-6 ligand exhibited recognition for the enantiomers of NapEtHClO4.
Eight new macrocyclic ligands containing the pyrimidine subcyclic unit (3-10, Figure 1) have been prepared. Two of these new crown ethers are chiral. Pyrimidino-crowns 3-8 were prepared by treating the di-tosylate derivative of the appropriate oligoethylene glycol with 4-methoxy-5-raethyl-2,6-pyrimidinedimeth-anol in basic conditions. The yields were in the 30-50% range giving the crowns as viscous oils. Chiral dimethyl-substituted pyrimidino-crown 9 was prepared from 4-methoxy-5-methyl-2,6-pyrimidinedimethyl di-tosylate and chiral dimethyl-substituted tetraethylene glycol. Treatment of dimethyl 4-methoxy-5-methyl-2,6-pyrimidinedicarboxylate with the diamine derivative of chiral dibenzyl-substituted tetraethylene glycol gave the chiral dibenzyl-substituted pyrimidino-crown diamide 10. Starting 4-methoxy-5-methyl-2,6-pyrimidinedi-methanol was prepared by a six step process from acetamidine hydrochloride and diethyl oxalpropionate.
