The synthesis of oxime-and-amide bis-chelate ligands.
(2014)In this part of the thesis our intention was to pave the way for the synthesis of pentadentate ligands with the bis-chelate methyl-hydroxyacetamide binding centre augmented with a flexible pendant arm that may provide ... -
Synthesis of polycyclic hydantoin derivitaves and peptides.
(2008)Cyclic cage compounds have attracted much attention in pharmaceutical studies. The lipophilic nature of these compounds plays an important role in facilitating the crossing of the cellular membranes, including the blood ... -
Synthesis of prenylated benzoquinones.
(2010)The research presented in this study demonstrates the critical role that organic synthesis plays in natural product chemistry. The biological activity demonstrated by 2-methyl-6-(3-methyl-2- butenyl)benzo-1,4-quinone ... -
Synthesis of pyridines by using metal oxides on zirconia support as catalysts.
(2017)Abstract available in PDF file. -
Synthesis of quinoline derivatives by a Doebner-von Miller reaction using a Ag(I)-exchanged Montmorillonite K10 catalyst.
Quinolines play an important role in organic chemistry, as exemplified by their extensive application as biologically and pharmacologically active compounds. However, current methods available to access quinoline compounds ... -
Synthesis of Ru(II) and Co(II) NNN-pyridine based complexes and their activity in the oxidation of n-octane.
(2017)Abstract available in PDF file. -
Synthesis of sulfur- and nitrogen-based boranes and their hydroboration reactions.
(2004)No abstract available. -
The synthesis of xanthene-based transition metal complexes and their application in the oxidation reaction of n-octane.
(2014)The oxidation of alkanes into valuable products such as alcohols, ketones and aldehydes is very important to industry for detergents and perfumes. One of the challenges with alkanes is their inertness which results from ... -
Synthesis of xanthoxal.
(1999)The aim of this project was to synthesize xanthoxal, a natural product which is a possible abscisic acid precursor. The xanthoxal will serve as a vital link: in a study on the biosynthesis of abscisic acid in plants. This ... -
The synthesis, characterisation and antibacterial activity of benzimidazole-oxadiazole hybrids.
(2022)Abstract available in PDF. -
Synthesis, characterisation and antibacterial activity of quinoline chalcone hybrids.
(2019)Abstract available in PDF. -
Synthesis, characterisation and antibacterial activity of substituted 2-quinoline thiosemicarbazones.
(2017)Fifteen quinoline-2-thiosemicarbazone hybrid derivatives were synthesised in a three step reaction involving formation of the quinoline, oxidation of the 2-methyl group and condensation to the thiosemicarbazones. The ... -
Synthesis, characterisation and biological activities of homoisoflavonoids.
(2012)Fifteen homoisoflavonoids (3-17) were synthesised using the base-catalysed aldol condensation, thirteen of which were of the 3-benzylidene-4-chromanone type and the remaining two of the 3-benzyl-4-chromanone type. The ... -
Synthesis, characterisation and biological studies of copper(I) and copper(II) pyridinyl Schiff base complexes.
(2019)Coordination complexes have numerous applications ranging from industrial processes to pharmaceuticals. Schiff base ligands, along with copper(I) and copper(II) metal complexes have been investigated and reported in the ... -
Synthesis, characterization and antibacterial evaluation of novel substituted galactose thiazolidin-4-ones.
(2014)In this study, fifteen novel thiazolidinone derivatives were synthesized from galactose. In general it was observed that stereoselectivity for most of the 2R diastereomers was better than the 2S diastereomers. All compounds ... -
Synthesis, characterization and antioxidant activity of prenylated and fluorine based flavonoids.
(2013)Twenty flavonoids II-XXI were successfully synthesized using the Claisen-Schmidt condensation reaction between 2-hydroxy and 3-hydroxyacetophenone with various substituted fluorobenzaldehydes. The twenty flavonoids ... -
Synthesis, characterization and application of supported nickel catalysts for the hydrogenation of octanal.
(2010)Three nickel based catalysts were prepared by the impregnation method (Ni/Al2O3 and Ni/SiO2) and co-precipitation method (Ni/ZnO). The catalysts were characterized by XRD, ICP-OES, BET-surface area and pore volume, SEM, ... -
The synthesis, characterization and electrocatalytic behaviour of novel cobalt (II) and iron (II) phthalocyanines bearing benzopyrone, benzoxazole, tetrahydropyran and furan moieties.
(2015)The fabrication of metallophthalocyanine (MPc)-based modified electrodes has proven to be effective for the electrocatalysis of various bio-analytes and pollutants. The selectivity of these chemically modified electrodes ... -
