Abstract:
AbstractAcyclic quaternary carbon stereocenters occur frequently in natural products, bioactive molecules, and pharmaceutical compounds. Construction of a carbon stereogenic center attached to four different carbons with defined spatial arrangement is a daunting challenge in asymmetric catalysis. Significant efforts have been directed towards the stereoselective construction of such acyclic quaternary carbon stereocenters. In particular, catalytic generation of acyclic quaternary carbon stereocenters through functionalization of unsaturated hydrocarbons is an extremely attractive approach beca

Abstract:
The largest Lapacian eigenvalue ?1 of the molecular graph is a quantity important in the theory of the photoelectron spectra of saturated hydrocarbons. It is shown that in the case of alkanes, the presence or absence of quaternary carbon atoms is the main structural feature on which ?1 depends. Within sets of all alkanes with a given number of carbon atoms the species (with and without quaternary carbons atoms) whose ?1-values are minimal and maximal are determined.

Abstract:
An efficient enantioselective construction of quaternary carbons including spiro carbons is an area of intense interest due to the importance of these units as components of biologically active natural products. Prominent methods are presented for the synthesis of chiral, nonracemic quaternary carbon centers by (i) stereospecific rearrangement of optically active epoxides, (ii) enzyme-catalyzed resolution, and (iii) hypervalent iodine reagent-induced ipso-substitution of para-substituted phenol derivatives. These methods were applied to the total syntheses of fredericamycin A and discorhabdin

Els estereocentres de carboni quaternaris són omnipresents en molècules bioactives i farmacèuticament rellevants.

The main focus of the work contained within this thesis was to explore the possible use of novel organoboron chemistry in generating quaternary carbon centres, with the ultimate aim of developing new routes for the asymmetric synthesis of chiral quaternary carbon centres. Chapter 1 contains a general introduction to the literature of organoboron chemistry, focusing particularly on organoboron reactions that contain 1, 2 - boron to carbon migrations. Chapters 2 and 3 contain attempts at generating tertiary alkyl groups bonded to boron in an asymmetric fashion. Chapter 2 specifically deals with

Abstract:
Multi-substituted optically pure cyclopropanes are important motifs present in many agrochemicals, pharmaceuticals and materials employed in manifold applications. Their synthesis is challenging due to both the strained conformation and the need to control both the relative and absolute stereochemistry. This thesis describes an investigation of the scope of the Wadsworth-Emmons cyclopropanation, highlighting it as a potential efficient methodology for diastereoselective and enantiospecific synthesis of these valuable ring systems.

Conjugated olefins are readily available and inexpensive starting materials and their functionalization offers a rapid access to many important building blocks for organic synthesis. The functionalization of these olefins by asymmetric catalytic methods for the formation of C-C and C-X bonds is an active area of research. Major advances in this field are not only triggered by the development of new catalysts but also by engineering of new acceptor olefins. In our lab we have successfully developed acceptor olefins appended to alkoxyimidazoles as a novel template. Using these templated acceptor
