(Cont.) Our studies indicate that unfavorable peri-interactions between the imine substrate and the Lewis acid may be the conformation-controlling element for nucleophilic additions to imines. On the other hand, detailed mechanistic studies of the Mukaiyama aldol reaction suggest a reaction pathway involving an intermediate with a coplanar aldehyde-Lewis acid conformation. These studies demonstrate the broad scope and the high efficiency with which the chiral information is transferred from the planar-chiral Lewis acid to its substrates. Consequently, the turnover step (regeneration of the active Lewis acid) represents the last hurdle to be addressed for achieving asymmetric Lewis acid catalysis. Part III of this thesis describes miscellaneous applications that have been discovered during the course of the development of 1,2-azaborolyl-based planar-chiral Lewis acids. In Chapter 7, we present a surprisingly mild and versatile method for palladium-catalyzed Suzuki cross-couplings of aryl chlorides in the presence of a triarylphosphine. With this catalytic system, both sterically demanding and electronically deactivated aryl chlorides can be efficiently coupled with a range of boronic acids in good yields, and coupling of activated aryl chlorides can be accomplished at room temperature. In Chapter 8, we report the synthesis and characterization of novel 1,2-azaborines and their potential as benzene surrogates.

Progress in Boron Chemistry, Volume I is a 10-chapter text that covers the advances in the chemistry of various boron compounds and their applications. The opening chapter deals with the chemistry of compounds containing boron-boron bonds, followed by a brief overview of some aspects of the coordination chemistry of boron. The subsequent chapters discuss the molecular structures of boron hydrides and the chemotherapeutic potential of boron compounds. Other chapters explore the chemistry of other boron compounds, including heteroaromatic boron compounds, organoperoxyboranes, organoboron heterocycles, and boronic acids. The concluding chapter describes the NMR studies of boron compounds. This book is of value to organic, inorganic, and analytical chemists.

Pyridines and triazines are nitrogen heterocycles found in all fields of the chemical realm. These aromatic compounds readily undergo nucleophilic aromatic substitution reactions. Nitrogen heterocycles appear in therapeutics, reactive dyes, herbicides, catalysts, and others. Exploration of pyridines and triazines in our laboratory, resulted in novel compounds with potential applications. A triazine ligand was developed containing pyrazolone and hydrazine groups, capable of binding to first row transition metals. Copper (II), nickel (II), and zinc (II) formed chelates through a unique 6,5 oxygen to metal binding ring systems. The chelating ability of this ligand led to promising results in its antioxidant ability, and cellular toxicity. (Chapter 1). Homo- and heterodimeric peptide macrocycles were synthesized and characterized. The facile route for the preparation of these compounds enable for rapid and selective transformations of diverse dimeric macrocycles. Analysis via mass spectrometry, NMR spectroscopy, and X-ray diffractometry determined the formation of 24-membered macrocycles. Glycine, and Lphenylalanine amino acid residues were incorporated into the macrocycles as well as substituted hydrazines as amino acid side chain mimics. These compounds find potential applications in a broad field of biological sciences. (Chapter 2). Finally, four members of a class of pyridine containing macrocycles bearing electron withdrawing groups in the 4-position (CN, NO2, Cl, CF3), were synthesized as targets for metal chelation and catalysis. (Chapter 3).
