Approaches toward the synthesis of lactonamycin utilising a new benzannulation reaction

Hussain, Jakir January 2013 (has links)
The Bull-Hutchings-Quayle (BHQ) reaction is a novel method for the synthesis of 1-(bromo/chloro)napthalenes from 2-allyphenyl-2’,2’,2’-tri(bromo/chloro)acetates. The reaction is also known as Atom Transfer Radical Cyclisation-Benzannulation (ATRC-Benzannulation). The ATRC-Benzannulation of structurally diverse 2-(cyclohex-1-en-1-ylmethyl)phenyl 2’,2’,2’-trichloroacetates in the presence of 1,3bis-(2,6diisopropylphenyl)imidazolium copper(I) chloride [“Nolan NHC-CuCl”] complexes, using microwave or thermolytic methods, afford a range of 9-chloro-1,2,3,4-tetrahydroanthracenes. Efficient ATRC-Benzannulation has been restricted to microwave conditions so a thermolytic method has been developed as an alternative. Application of BHQ methodology toward the synthesis of the core structure of lactonamycin are reported. Stille, Suzuki and Sonogashira cross-coupling methods were used for the synthesis of diene precursors of a lactonamycin analogue. [4+2] Diels-Alder cycloadditions have been investigated with the diene precursors and various dienophiles. 1-Chloroquinone has been displaced with para-methoxyphenol to generate 1-para-methoxyquinone. CAN mediated oxidation of 1-para-methoxyquinone has yielded 1-hydroxyquinone.

Agregace aminokyselin a podobných molekul v přítomnosti fosfolipidové monovrstvy / Clustering of aqueous aminoacids and similar molecules in the presence of phospholipid monolayers

Kukharchuk, Alexandra January 2016 (has links)
Amino acid phenylalanine plays a key role in numerous biological processes and is also involved in amyloid fibril diseases. The aim of the thesis is to deepen our understanding of its behavior and partitioning at interfaces, and to investigate its clustering. Classical atomistic molecular dynamics simulations were performed for phenylalanine and three other aromatic molecules which chemical structure is derived from it - phenylglycine, phenylacetic acid and tyrosine. Molecules are simulated at both water-air and at water-DPPC-air interfaces. Phenylalanine, phenylglycine and phenylacetic acid demonstrate surface activity at the water-air interface, whereas tyrosine is not surface active. All molecules interact with the lipid monolayer at the water-DPPC-air interface but only phenylalanine penetrates deep into the monolayer. Formation of transient clusters is observed in the interfacial regions, mostly for phenylalanine. Powered by TCPDF (www.tcpdf.org)
