This Thesis is divided into three parts: Introduction (Chapter 1), Result and Discussion (Chapter 2) and Experimental (Chapter 3). The Introduction (Chapter 1) provides a review of the recent literature relating to the 1,3dipolar cycloaddition reactions. ItÃ‚Â· covers nitrones, azomethine ylides and azomethine imines. The Result and Discussion. section (Chapter 2) deals with the author's work which is . concerned with developing four novel multicomponent cascade reactions.

Abstract:

This thesis is divided into three parts. Part one presents an overview of isocyanide based multicomponent reactions, with a particular emphasis placed upon bifunctional substrates and novel nucleophilic partners for the Ugi reaction. Part two discusses the development of three-component reactions between N- alkyloxazolidines, isocyanides and carboxylic acids. This reaction is then further developed to allow it to be carried out in a four-component manner from an aminoethanol and carbonyl compound rather than an N-alkyloxazolidine.

Abstract:

Many phenomena determining the microstructure of a tool steel and consequently the properties of the material, are governed by multicomponent diffusion. The diffusion driven reactions that take place during, for example, tempering of a hot-work tool steel or when the microstructure develops during hot isostatic pressing of cold-work tool steel, are dependent on the types and amounts of alloying elements. In order for computational methods to be usable, these alloying effects need to be understood and incorporated in the models. In this work the influence of some typical tool steel alloying ele

Abstract:

Multicomponent reactions (MCRs) are processes that show high atom and step economy; two different parts of my thesis were linked by MCRs. In the first part, levulinic acid was converted into a variety of bicyclic nitrogen heterocycles passing by an Ugi reaction. The obtained intermediate was then converted in the final product via a simple SN2 cyclization. The second part, instead, was dedicated to the obtainment of organo-catalysts structurally based on secondary and tertiary amine groups. First attempts, to get the latter in bicyclic structures, involved a starting MCR with L-prolinol, but

Abstract:

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

Abstract:

No capítulo 1 apresentamos uma síntese eficiente de compostos 5-organoteluro-1H- 1,2,3-triazóis realizada via reação de cicloadição [3+2] entre azidas orgânicas e alquinos substituídos com organotelúrio. Além disso, os 5-organoteluro-1H-1,2,3-triazóis foram funcionalizados na posição 5 do anel triazólico por reação de acoplamento cruzado de Sonogashira. A regioquímica dos produtos de cicloadição foram descritas com base em experimentos de RMN, cálculos teóricos e cristalografia de raio-x. Apresentamos uma proposta mecanística para a cicloadição mediada por cobre, baseada em experimentos de esp
