Synthesis of Isothiocyanates Using DMT/NMM/Tso− As a New Desulfurization Reagent
molecules Article Synthesis of Isothiocyanates Using DMT/NMM/TsO− as a New Desulfurization Reagent Łukasz Janczewski 1,* , Dorota Kr˛egiel 2 and Beata Kolesi ´nska 1 1 Faculty of Chemistry, Institute of Organic Chemistry, Lodz University of Technology, Zeromskiego 116, 90-924 Lodz, Poland; [email protected] 2 Department of Environmental Biotechnology, Faculty of Biotechnology and Food Sciences, Lodz University of Technology, Wolczanska 171/173, 90-924 Lodz, Poland; [email protected] * Correspondence: [email protected] Abstract: Thirty-three alkyl and aryl isothiocyanates, as well as isothiocyanate derivatives from esters of coded amino acids and from esters of unnatural amino acids (6-aminocaproic, 4-(aminomethyl)benzoic, and tranexamic acids), were synthesized with satisfactory or very good yields (25–97%). Synthesis was performed in a “one-pot”, two-step procedure, in the presence of organic base (Et3N, DBU or NMM), and carbon disulfide via dithiocarbamates, with 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4- methylmorpholinium toluene-4-sulfonate (DMT/NMM/TsO−) as a desulfurization reagent. For the synthesis of aliphatic and aromatic isothiocyanates, reactions were carried out in a microwave reactor, and selected alkyl isothiocyanates were also synthesized in aqueous medium with high yields (72–96%). Isothiocyanate derivatives of L- and D-amino acid methyl esters were synthesized, under conditions without microwave radiation assistance, with low racemization (er 99 > 1), and their absolute configuration was confirmed by circular dichroism. Isothiocyanate derivatives of natural and unnatural amino acids were evaluated for antibacterial activity on E. coli and S. aureus bacterial strains, where the Citation: Janczewski, Ł.; Kr˛egiel,D.; most active was ITC 9e. -

NAC/AEGL Committee Meeting Minutes, December 2007
National Advisory Committee (NAC) for Acute Exposure Guideline Levels (AEGLs) for Hazardous Substances December 5-7, 2007 Meeting-44 Highlights Orlando World Center Marriott 8701 World Center Drive Orlando, FL INTRODUCTION Ernest Falke distributed a CD containing the most recent Technical Support Documents for all AEGL program chemicals that are proposed, interim, or final status. Dr. Falke also stated that the Prepublication Copy of NAS Volume 6 was released in September, 2007, and that the published volume should be available for distribution by the March meeting. Paul Tobin informed the group that the NAC/AEGL committee was recognized by the FACA awards program twice (last year and this year). There are 27 EPA FACAs, and only the NAC/AEGL was recognized twice; a total of only 3 EPA FACAs were recognized. Specifically, the NAC/AEGL was recognized for timeliness of Federal Register notices, transparency of the process, public input (both via the meeting and the Federal Register), and international impact. The draft NAC/AEGL-43 meeting highlights were reviewed. Due to a rounding error, the 30-minute AEGL-3 value for dichlorosilanes should be 110 ppm, not 105 ppm. A motion was made by Bob Benson and seconded by John Hinz to accept the minutes as proposed with the aforementioned correction. The motion passed unanimously by a show of hands (Appendix A). The Final NAC/AEGL-43 meeting highlights are attached (Appendix B). The highlights of the NAC/AEGL-44 meeting are summarized below along with the Meeting Agenda (Attachment 1) and the Attendee List (Attachment 2). The subject categories of the highlights do not necessarily follow the order listed in the NAC/AEGL-44 Agenda. -
Intramolecular Ene Reactions of Functionalised Nitroso Compounds
INTRAMOLECULAR ENE REACTIONS OF FUNCTIONALISED NITROSO COMPOUNDS A Thesis Presented by Sandra Luengo Arratta In Partial Fulfilment of the Requirements for the Award of the Degree of DOCTOR OF PHILOSOPHY OF UNIVERSITY COLLEGE LONDON Christopher Ingold Laboratories Department of Chemistry University College London 20 Gordon Street London WC1H 0AJ July 2010 DECLARATION I Sandra Luengo Arratta, confirm that the work presented in this thesis is my own. Where work has been derived from other sources, I confirm that this has been indicated in the thesis. ABSTRACT This thesis concerns the generation of geminally functionalised nitroso compounds and their subsequent use in intramolecular ene reactions of types I and II, in order to generate hydroxylamine derivatives which can evolve to the corresponding nitrones. The product nitrones can then be trapped in the inter- or intramolecular mode by a variety of reactions, including 1,3-dipolar cycloadditions, thereby leading to diversity oriented synthesis. The first section comprises the chemistry of the nitroso group with a brief discussion of the current methods for their generation together with the scope and limitations of these methods for carrying out nitroso ene reactions, with different examples of its potential as a powerful synthetic method to generate target drugs. The second chapter describes the results of the research programme and opens with the development of methods for the generation of functionalised nitroso compounds from different precursors including oximes and nitro compounds, using a range of reactants and conditions. The application of these methods in intramolecular nitroso ene reactions is then discussed. Chapter three presents the conclusions which have been drawn from the work presented in chapter two, and provides suggestions for possible directions of this research in the future. -

Revised 24 th May 2015. Published 4 th September 2015. Summary World War I was a conflict where chemical warfare was first used on a massive scale. The earliest chemical attack occurred on the Western Front in October 1914 in Neuve Chapelle, but its effects were so minimal that the Allies learned about it only after the war from German documents. The attack in the Bolimow area, carried out by the Germans against the Russian army with artillery shells containing gas T (xylyl and benzyl bromides), was therefore the first attack on a massive scale recorded on the victim side. The attack, which occurred after it, made it possible to obtain some tactical success, but without a strategic breakthrough. Some of the later German attacks on the Eastern Front where chlorine was used proved to be more effective, but despite many victims there was not any major strategic success achieved. The Russians did not take attempts to use chemical weapons in the World War I. Key words: respiratory irritants; irritant gases; chemical warfare agents; riot control agents; World War I INTRODUCTION comfort to acute airway and lung injury and even death. -
