Abstract:

The oxidative coupling of 2,6-di-t-butylphenol under mild reaction conditions is well documented and the subject of many patents. However, the coupling of other monoand di- substituted phenols is not as well documented and thus there is scope for further investigation for providing a convenient, environmentally friendly and economically viable method for the oxidative coupling of these phenols. In this study, the oxidative coupling of a variety of alkylated phenolic substrates, 2-tbutylphenol, 2,6-di-t-butylphenol, 2,4 -di-t-butylphenol and ,4-dimethylphenol, using a range of different oxidizi

Abstract:

Palladium catalyzed reactions of derivatives of 2,4-diiodophenol are explored. Coupling reactions with a series of terminal alkynes and formylation are found to be efficient and regioselective. Coupling with stananne reagents and alkenes do not work. The nature of the oxygen protecting group is critical. The phytotoxic natural product, Eutypine, is synthesized by using regioselective formylation and alkyne coupling. An approach to the plant antimicrobial compound Plicatin B is examined.

Abstract:

Incorporation of phenylpropanoids into the plant polymer lignin occurs by a radical coupling mechanism catalysed by the enzyme peroxidase. Generation of the parent radical requires reduction of the enzyme intermediate compound I, which can be monitored by electron spin resonance (ESR) spectroscopy. It was found that the substituted cinnamyl alcohols were more easily oxidised than their corresponding acids and esters. For all phenylpropanoids, ease of oxidation increased with methoxyl substitution. The dehydrodimers, which represent the products of initial coupling, showed a similar trend with

In recent years, great efforts have been devoted to the elaboration of novel synthetic methodologies for the construction of N-heterocycles such as oxindoles and indoles. Reported in 2009 by the Taylor group, access to oxindole scaffolds has been successfully demonstrated via a copper(II)-mediated oxidative coupling approach.

Recently, organosilicon compounds have emerged as an attractive alternative to these established reagents, benefitting from low toxicity, low cost, and general ease of handling. While the fundamental reactivity of arylsilane reagents (Ar-SiR3) is well known, their role in transition metal-catalysed reactions is generally less well studied.

The synthesis of compounds containing α-arylated quaternary stereogenic centres is a significant synthetic challenge. This thesis describes the development of an organocatalytic methodology for the direct construction of this motif through the Michael addition of carbon-centered pro-nucleophiles to highly reactive and unstable ortho-benzoquinones. Proof-of-principle for the base catalysed Michael addition to ortho-quinones was established with stable 1,2-naphthoquinone (Chapter 2), however typical orthobenzoquinones were found to be too unstable to use in this process. Accordingly an oxidative

Abstract:

Improving diversity of food systems by targeting whole grain cereals, pseudo-cereals, and millets is essential to enhance nutritional qualities beyond macro and micronutrient balance and to address emerging global food and nutritional security-linked public health challenges. However, human health relevant nutritional parameters of whole grains vary widely among species, genotypes, growing conditions, and further due to different processing methods. Therefore, it is important to screen human health relevant nutritional parameters of these whole grains prior to targeting them for wider public h
