The synthesis of 3-allyl-4-ethyl-2- (1'-hydroxyethyl)-1-methoxynaphthalene and its behaviour towards base- and palladium-promoted cyclisation under aerobic and anaerobic conditions
(University of the Western Cape, 2005)Over the years, Giles and co-workers have established that, upon treatment with potassium tert-butoxide, tetra-substituted naphthalenes undergo cyclisations to afford naphthopyrans. It was suggested that these base-induced ... -
The synthesis of analogues of the Anti-TB (agent: Diospyrin)
(University of the Western Cape, 2005)Diospyrin, a bisnaphthyl quinone molecule with proven anti-TB activity can be retrosynthetically formulated into two halves. In this work, the analogue chosen to be synthesized was similarly retrosynthesized into two halves. ... -
Synthesis of binary and ternary Pd-based Nanocatalysts for alcohol oxidation in alkaline media for fuel cell application
(University of the Western Cape, 2020)This study explores the use of UV-assisted reduction method to synthesise the catalysts, aiming at reducing synthesis time. The Pd and Au catalyst loading is kept at 5 wt% in order to reduce the cost associated with high ... -
Synthesis of DMSO based silver nanoparticles for application in wound healing
(University of Western Cape, 2021)Silver nanoparticles (AgNPs) apart from being chemically significant, have shown a lot of health benefits, the most studied being their anti-bacterial and anti-inflammatory properties. These biological properties can be ... -
Synthesis of metal modified Mesoporous Zeolites catalysts: application in conversion of Olefins to Valuable liquid products
(University of the Western Cape, 2016)The effects of temperature, synthesis duration and silica source were studied to obtain suitable conditions for our laboratory experiment concerned with the synthesis of MCM-41 catalyst. The transformation of 1-hexene was ... -
The synthesis of methoxy-2-hydroxy-1,4- naphthoquinones and their reaction with aliphatic aldehydes under basic conditions.
(University of the Western Cape, 2003)Although literature reports on the synthesis of variously substituted 2-hydroxy-1 ,4- naphthoquinones appeared to be reasonable; in our hands difficulty was experienced in duplicating much of the work. In order to address ... -
Synthesis of peptide-loaded chitosan nanoparticles for the treatment of sexually transmitted infections (STI’s)
(University of Western Cape, 2019)Peptides are among the main drugs which attract much attention because of their great potential in treating sexually transmitted diseases and other chronic diseases. There has been a major challenge of delivering these ... -
The synthesis of prodrugs and novel analogues of Beta-sympathomimetic bronchodilators
(University of the Western Cape, 1998)Prodrugs are reversible derivatives of active drugs destined to undergo chemical or enzymatic transformation to the active drug after administration in order that the active drug may subsequently elicit the desired ... -
The synthesis of the cyclometallated palladium complexes and their applications in olefin oligomerization and in phenylacetylene oligomerization/polymerization
