Christof J. Kudla's Neuartige konjugierte Polymere: cyclopentadithiazol-, und PDF

By Christof J. Kudla

ISBN-10: 3739204168

ISBN-13: 9783739204161

Im ersten Kapitel dieser Arbeit wird die Synthese eines 7,7-Dialkyl-cyclopenta[1,2-d:4,3-d´]dithiazol-2,5-diyl-Monomers (CPDTz) als neuer Baustein zur Synthese konjugierter Polymere beschrieben. Es wird gezeigt, dass die insgesamt neunstufige Syntheseroute mit einer Gesamtausbeute von beachtlichen 30 % durchgeführt werden kann. Aus dem CPDTz-Monomer wurden verschiedene CPDTz-basierte konjugierte Polymere hergestellt. Ein CPDTz-Homopolymer zeigt dabei, im Vergleich zum bekannten Poly(cyclopentadithiophen) (PCPDT), ein erniedrigtes HOMO-Energieniveau bei verringerter Bandlücke.
Im zweiten Kapitel dieser Arbeit werden die Syntheseversuche für regioreguläre und regioirreguläre Poly(hexylthiazol)e beschrieben. Dabei wird im ersten Teil des Kapitels auf Monomersynthesen eingegangen. Ein hier neu vorgestellter Syntheseweg ermöglicht die Herstellung von bisher nicht zugänglichen Thiazol-Monomeren und bildet daher die Grundlage für die Herstellung von regioregulären und regioirregulären Poly(alkylthiazol)en.
Im zweiten Teil des zweiten Kapitels wird in den Versuchen zur Polymersynthese von regioregulären und regioirregulären Poly(alkylthiazol)en gezeigt, dass 1.) regioirreguläres Poly(hexylthiazol) durch Polymerisation unter Yamamoto-Bedingungen und 2.) HH-TT-regioreguläres Poly(hexylthiazol) durch Polymerisation unter Stille-Kelly-Bedingungen hergestellt werden kann, jedoch mit geringem Molekulargewicht von bis zu Mn = 4.000 g/mol.
Im dritten Kapitel dieser Arbeit wird die Synthese von isotaktischem Poly(9-alkyl1-9-alkyl2fluoren) beschrieben. Als Alkylketten dienen dabei Methyl- und Dodecylketten, zwei in ihrer Länge stark verschiedene Alkylketten. Die entwickelte Syntheseroute bietet die Möglichkeit, weitere isotaktische Poly(9-alkyl1-9-alkyl2fluoren)e mit unterschiedlichen Alkylketten herzustellen. Schlüsselschritte der vorgestellten Methode sind die Herstellung von AB-Typ-Monomeren und deren enantioselektive Auftrennung mittels chiraler, präparativer HPLC. Mittels 13C-NMR Spektroskopie konnte gezeigt werden, dass die auf diese Weise hergestellten isotaktischen Polymere eine hohe Isotaktizität aufweisen.

Get Methods of Non-α-Amino Acid Synthesis, Second Edition PDF

By Michael Bryant Smith

ISBN-10: 1466577894

ISBN-13: 9781466577893

Although much less universal than α-amino acids, non-α-amino acids—where the amino team isn't really at the carbon instantly adjoining to the carboxyl team yet is hooked up to a different carbon within the chain (for instance, the β, γ, δ carbon)—are elements of biologically very important molecules, are major within the pharmaceutical undefined, and are worthwhile beginning fabrics for plenty of parts of natural chemistry. because the booklet of the 1st variation of this booklet approximately two decades in the past, man made paintings dedicated to the education of non- α-amino acids has improved greatly.

Methods of Non-α-Amino Acid Synthesis, moment Edition has been broadly rewritten and reorganized, delivering an up to date assessment of recommendations and strategies for non-α-amino acid synthesis, quite these amino acids which are key man made intermediates or vital compounds of their personal correct. It makes a speciality of acyclic amino acids of C3–C10, but additionally aminoalkanoic carboxylic acids, aminoalkenoic acids, and aminoalkynoic acids. the recent version includes many up to date references and has a better emphasis at the organic significance of non-α-amino acids. as well as an array of man-made tools, the booklet bargains discussions on why non-α-amino acids are important.

The publication covers artificial tools that depend upon substituent refunctionalization, the conversion of cyclic precursors to acyclic amino acids, conjugate addition reactions, and enolate anion reactions and condensation reactions that bring about non-α-amino acids. It additionally examines reactions and techniques that bring about sturdy diastereoselectivity and enantioselectivity in the course of synthesis. A bankruptcy dedicated to biologically very important amino acids contains separate sections on GABA, GABOB, carnitine, DAVA, statine, and different major amino acids in addition to a brand new part on peptides and proteins that include non-α-amino acids. the ultimate bankruptcy addresses aminocyclic and heterocyclic amino acids.
