Abstract:
Carbonyls are an extremely important class of compounds and have been used in many different industries, including pharmaceuticals, fine chemicals, polymers and bulk commodities. The synthesis of carbonyl compounds through the oxidation of an alcohol or an alkene is an inherently straightforward protocol but despite this, oxidation reactions tend to be avoided industrially. This avoidance can be attributed to the lack of useful and safe methods for oxidation reactions. In this thesis, the oxidation of both alcohols and alkenes to their corresponding carbonyl compounds will be investigated usin

Chapter 2.3 describes the application of the NAP group to the protection of carboxylic acids. This group was again removed in the presence of benzyl esters from simple di-carboxylic acid substrates.

Abstract:
Palladium complexes have the ability to catalyse cross-coupling of two organic moieties through the formation of transient metal-carbon bonds, thus bringing them closer to each other to facilitate the formation of a new bond. Palladium-catalysed coupling reactions are one of the most important carbon-carbon forming reactions available to organic chemists and many of these reactions rely on the reactivity of aryl-palladium complexes. The investigation of new aryl-palladium precursors is thus of great interest, especially as more sustainable and economic methods can be developed. This thesis des

Palladium-catalysed carbonylative multicomponent reactions have proven useful for the synthesis of structurally diverse compounds. Carbon monoxide serves as an atom-efficient, one-carbon building block, which allows for further structural elaboration of the carbonyl compound. By varying the components of the carbonylative multicomponent reaction, considerable product diversity can readily be attained. However, due to the reluctance to use toxic CO gas, considerable efforts have been directed at exploring non-gaseous approaches. The work described in this thesis has mainly focused on the develo

Lavendamycin is a pentacyclic compound that possesses a quinoline-5,8-quinone AB ring linked to a b- carboline CED ring. The development of general routes to the synthetic equivalents of the lavendamycin AB quinoline system together with a linker atom, quinoline -2- carboxaldehydes, as well as to the lavendamycin DE indole ring system, namely tryptophan derivativ

Abstract:
Yes<br>Dehydroabietic acid (DAA) promotes palladium(0)‐catalysed cyclisations of arene‐tethered 1,7‐enynols and 1,m‐enynoates (m=6,7) to give fused carbocyclic dienes. 6,6,6,5‐Tetracyclic lactones are accessible by one‐pot cycloisomerisation/Diels–Alder reaction/lactonisation from 1,7‐enynols. Furthermore, asymmetric counteranion‐directed catalysis has been developed, which afforded an indene derivative with an all‐carbon quaternary stereogenic center.<br>NSFC.

Abstract:
Azaindoles are heterocyclic compounds scarce in nature, although interesting scaffolds in medicinal chemistry so there is a need of developing sustainable synthetic methods to obtain these cores. To date several methods involving more than one metal-catalysed reaction, like C-N cross-coupling,Heck coupling or the Sonogashira have been developed towards azaindoles. However, these methods require the use of amino-halopyridines as starting materials, which are difficult to prepare. This project aimed to surpass the need of functionalization of aminopyridines conceiving a fast and scalable one-p
