Download or read book New Applications of the Pauson Khand Reaction and Studies Towards the Synthesis of the Hamigerans written by Christian E. Madu and published by ProQuest. This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation is divided into two parts. The first part describes the dicobalt octacarbonyl mediated synthesis of medium sized rings via the intramolecular Pauson-Khand (IMPK) reaction. The cyclization of 1,8-enynes has proved to be difficult via the IMPK reaction due to entropy reasons. To overcome this limitation we attempted this cyclization in the presence of an ortho-buttressing group (t-butyl group) on the aromatic ring so as to reduce the conformationally allowed volume of the alkene arm of the substrate. The construction of the substrates started with O-alkenylation of the commercially available 3,5 di- tert-butyl-2-hydroxylbenzaldehyde and then the O-alkenylation products were alkynylated using ethynyl Grignard reagents to afford the corresponding enynes. These enynes successfully engaged in the both thermal and oxidative IMPK reaction to afford 5,7,6-tricyclic systems. With the parent enynes we observed diketo-compounds as the major product and traces of the expected PK product. When the alkyne arm of the enynes was substituted, the cyclization gave both the reduced PK product and the expected PK product. In general, the thermal mode gave a better diastereoselectivity when compared to the oxidative mode. Attempts to extend these result to a higher homolog to provide 5,8,6 tricyclic systems unfortunately failed. Thus this work describes a new methodology for the construction of medium (>6) sized rings via IMPK reaction. A second system was investigated which examined whether highly congested systems, related to those found in the hamigeran benzannulated terpenes, could be constructed. These experiments were successful, setting the stage for the studies described in the second section. The second part describes approach to the synthesis of the hamigerans by the application of the above developed IMPK methodology. The cyclization substrate was accessed from commercially available salicylic acid. The directed ortho metalation of the amide and treatment with iodine gave the iodo aryl amide. This was subsequently alkynylated using a Sonogashira cross-coupling reaction and then alkenylated via a Grignard reaction. The enyne was the subjected to IMPK reaction to afford the tricyclic core of the hamigerans.

Download or read book Metal Ions in Neurological Systems written by Wolfgang Linert and published by Springer Science & Business Media. This book was released on 2012-10-16 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal ions in the brain are a necessity as well as a poison. The presence of metal ions in the active sites of biological catalysts or metalloproteins and in the biological functioning of nucleic acids is very well documented and they are required for brain activity. On the other hand, metals are very effective in generating oxidative stress. This effect does not only play a role in immunology but also is the root of practically all neurodegenerative disorders by inducing disease via the death of neurons. Managing metal ions in the brain could therefore be an important strategy in the search for therapeutic agents used in the treatment of neurodegenerative diseases. This new title gives an overview to key topics in the area of metal ions in the brain. It focuses on the role of metal ions in neurological systems by describing their advantageous functions as well as their poisonous features. It is therefore of interest for scientists in biochemistry and biophysics, physiology, toxicology as well as for physicians focused on this topic.

Available in PDF, EPUB and Kindle. Book excerpt: Asymmetric C-H direct functionalization reactions are one of the most active and fascinating areas of research in organic chemistry due to their significance in the construction of molecular complexity without pre-activation, and the step economy and atom economy features in potential synthetic application. Distinguishing the reactivity among numerous C–H bonds in one single molecule represents one of the most challenging issues in organic synthesis and requires precise reaction design. As such, this field is now receiving increasing attention from researchers. This book provides the first comprehensive review of this field, summarizing the origin, mechanism, scope and applications of the asymmetric C-H bond functionalization reaction. It covers organocatalytic reactions and transition-metal-catalyzed reactions, as well as asymmetric C-H functionalization reactions not described in other books. Written by a leading expert in this field, the book is ideal for postgraduates and researchers working in organic synthesis, catalysis, and organometallic chemistry.
