Let us now turn to the experimental results to see if these predictions are borne out in fact. It has long been known that E2H reactions normally give preferentially anti elimination. For example, reaction of meso-stilbene dibromide with potassium ethoxide gives cis-bromostilbene (Reaction 7.39), whereas reaction of the D,L-dibromide gives the trans product (Reaction 7.40).lo2 A multitude of other examples exist-see, for example, note 64 (p. 355) and note 82 (p. 362). E2H reactions do, however, give syn elimination when: (1) an H-X di- hedral angle of 0" is achievable but one of 180" is not or, put another way, H and X can become syn-periplanar but not trans-periplanar ; (2) a syn hydrogen is much more reactive than the anti ones; (3) syn elimination is favored for steric reasons; and (4) an anionic base that remains coordinated with its cation, that, in turn, is coordinated with the leaving group, is used as catalyst. The very great importance of category 4 has only begun to be fully realized in the early 1970s. lo2 P. Pfeiffer, 2. Physik. Chem.

The thyroid gland is found in the neck, below the thyroid cartilage (which forms the laryngeal prominence, or "Adam's apple"). The isthmus (the bridge between the two lobes of the thyroid) is located inferior to the cricoid cartilage. The thyroid gland controls how quickly the body uses energy, makes proteins, and controls how sensitive the body is to other hormones. It participates in these processes by producing thyroid hormones, the principal ones being triiodothyronine (T ) and thyroxine which can sometimes be referred to as tetraiodothyronine (T ). These hormones 3 4 regulate the rate of metabolism and affect the growth and rate of function of many other systems in the body. T and 3 T are synthesized from both iodine and tyrosine.

  • Oxidized Sulfur Functionalized Polymers Via Admet Polymerization
    OXIDIZED SULFUR FUNCTIONALIZED POLYMERS VIA ADMET POLYMERIZATION By TAYLOR WILLIAM GAINES A DISSERTATION PRESENTED TO THE GRADUATE SCHOOL OF THE UNIVERSITY OF FLORIDA IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY UNIVERSITY OF FLORIDA 2015 © 2015 Taylor William Gaines To Mom and Steve ACKNOWLEDGMENTS There are so many who have been contributors to my success and I would like thank all of them. This doctorate involved not only the four years in graduate school, but everything in life up until the degree’s competition. I have always tried to remember life’s little lessons. I cannot mention everyone who deserves thanks; otherwise, this section would comprise the entire document. But I believe those mentioned below have had the most profound effect on my life and especially my education. I must start by first thanking my grandparents, Iris and Tony Pritchard, who were essential to my early upbringing in western North Carolina. These two were hardworking, small town, blue-collar, and family oriented. My grandfather was in the automotive repair industry, and my grandmother worked 47 years for the same furniture company. They grew up in the depression, knew the value of hard work, family, and how to make a little money go a long way. I can honestly say they never met a stranger, and they were kind to everyone. I am most appreciative of the values these two instilled in me, including dedication, the importance of family, and the value of hard work. They loved us unconditionally and spoiled my brother and me, probably too much at times.

  • Development of a Protecting Group for Sulfate Esters
    Development of a Protecting Group for Sulfate Esters. Andrew D. Proud. FIIJ The University of Edinburgh. II,9J C) Abstract: This work describes the development of a protecting group for sulfate monoesters in carbohydrates. After initial trial studies, the trifluoroethyl ester was selected as a suitable protecting group. The ester was formed from the sulfate by treatment with trifluorodiazoethane. This protection method is shown to be compatible with other common protecting groups used in carbohydrate chemistry. The protecting group is proven to be stable to the manipulations of many other protecting groups. The utility of monosaccharides incorporating protected sulfate esters in synthesis has been examined. It has been proven that they are useful and versatile building blocks in the synthesis of more complex structures. Selective cleavage of the trifluoroethyl ester was achieved with potassium tert-butoxide. The mechanism for this deprotection reaction has been studied and this investigation has led to the advancement of alternative deprotection methods. I declare that, this Thesis has been composed by m,yself and that the work is my own. Andrew David Proud. Acknowledgements: I would like to thank my supervisor Prof. Sabine Flitsch for her help and support throughout this project. I also wish to thank Dr. Jeremy Prodger, of GlaxoWelicome and Prof. Nick Turner of The University of Edinburgh for their many suggestions and useful advice. I wish to acknowledge the EPSRC and GlaxoWelicome for financial support. I wish to thank all the people that run the NMR and X-ray crystallography services at Edinburgh University but especially John Miller and Simon Parsons.
