Streszczenie:

Transition metal-catalysed cross coupling chemistry is a valuable tool for synthetic organic chemistry, enabling the preparation of compounds of great interest. The catalytic metal of choice is usually palladium, which generally offer better performances in term of catalytic activity and easy handling. On the other hand, the use of nickel in this class of reactions is gaining attention, as it would provide more economically and environmentally sustainable processes. Deprotonative cross couplings are a subgroup of these reactions, in which the nucleophile is generated in situ by direct deproton

The antiviral or anticancer activities of C-5 modified pyrimidine nucleoside analogues validate the need for the development of their syntheses. In the first half of this dissertation, I explore the Pd-catalyzed cross-coupling reaction of allylphenylgermanes with aryl halides in the presence of SbF5/TBAF to give various biaryls by transferring multiple phenyl groups, which has also been applied to the 5-halo pyrimidine nucleosides for the synthesis of 5-aryl derivatives. To avoid the use of organometallic reagents, I developed Pd-catalyzed direct arylation of 5-halo pyrimidine nucleosides. It

The purpose of this study was to develop new catalytic methods to mediate carbon-carbon bond forming reactions with imines under mild conditions and in a general manner. We found that copper catalysts were compatible in cross-coupling of a range of mild organometallic reagents, providing simple, efficient routes to alpha-substituted amides and amines.<br>Chapter 2 of this thesis describes a new copper-catalyzed multicomponent synthesis of alpha-substituted amides. This reaction was developed based upon previous work in this laboratory, which showed that palladium catalysts were competent in St

In the following thesis, new methodologies towards the synthesis of a range of sulfonyl (-SO<sub>2</sub>-) containing functional groups are documented. These methods utilise easy-to-handle sulfur dioxide surrogates, such as DABSO (vide infra), and exploit palladium catalysis as a new mechanistic protocol for the incorporation of the -SO2- unit. <b>Chapter 1</b> is a literature review surveying sulfur dioxide in organic synthesis, the established uses of SO<sub>2</sub> surrogates and the importance of the sulfonyl moiety in chemistry.

This research focuses on promoting nickel-based catalysts by visible-light illuminated gold and palladium nanoparticles in fine organic synthesis. Using lignin model compound cleavage as the model reaction, the performance of three distinct systems, in-situ formed Ni(OH)2 on ZrO2 supported Au NPs, non-plasmonic NiPd alloy NPs supported on ZrO2 and the mechanical mixture of ZrO2 supported Au NPs and Ni NPs are investigated. Ultra-low palladium loading on sodium titanate sheets for Heck cross-coupling reaction under visible light is also studied. This research has provided innovative findings in

Chemical modification of proteins is critical for many areas of biochemistry and medicine. Several methods for site-selective protein modification are reported in this Thesis that are useful in accessing both natural and artificial protein architectures. Multiple, complementary methods for the conversion of cysteine to dehydroalanine are described. Dehydroalanine is used as a general precursor to several post-translational modifications and glycosylation, polyprenylation, phosphorylation, and lysine methylation and acetylation are all accessible. These modifications and their mimics were explo

The previously described 2-aryl-4-chloro-3-iodoquinolines were prepared following literature procedure and in turn converted to the corresponding hitherto unknown 2-aryl-3-iodo-4-(phenylamino)quinoline derivatives using aniline in refluxing ethanol. These 2-aryl-3-iodo-4-(phenylamino)quinolines were reacted with allybromide in ethanol at room temperature to afford 4-(N,N-allylphenylamino)-2-aryl-3-iodoquinoline derivatives. The 2-aryl-3-iodo-4-(phenylamino)quinoline and 4-(N,N-allylphenylamino)-2-aryl-3-iodoquinoline derivatives were subjected to metal-catalysed carbon-carbon bond formations.

Our group has developed a strategy for the synthesis of benzofused carbocycles and heterocycles through tandem palladium-catalyzed reactions of gem-dibromoolefins. In these syntheses, one bromide undergoes a Pd-catalyzed cyclization reaction, and the other participates in an orthogonal inter- or intramolecular Pd-catalyzed reaction to functionalize or annulate that ring, respectively. Chapter 1 describes the pairing of an intramolecular C–N bond forming reaction (the Buchwald-Hartwig coupling) with an intramolecular direct arylation for the synthesis of fused indole derivatives.
