Abstract:

Homochiral AB segments for (+)- and (–)-pillaromycinone were prepared in 11 steps from 2-acetylfuran. The synthesis featured an intramolecular Diels–Alder reaction of a 2,5-disubstituted furan and a hydroxyl-directed homogeneous hydrogenation of the tetrasubstituted alkene double bond of two enones. The CD segment was attached by a modified Staunton–Weinreb annulation to produce the desired homochiral tetracycle 21c related to (+)-pillaromycinone. An unusual acetonide migration enabled the synthesis of a tetracyclic model for premithramycinone.

Abstract:

Many of life’s molecules including proteins are built from chiral building blocks. What drove homochiral building block selection? Simulations on demi-chiral proteins containing equal numbers of d- and l-amino acids show that they possess many modern homochiral protein properties. They have the same global folds and could do the same biochemistry, with ancient, essential functions being most prevalent. They could synthesize chiral RNA and lipids which formed vesicles. RNA eventually combined with proteins creating ribosomes for more efficient protein synthesis, and thus, life began. Increased native state stability from homochiral secondary structure hydrogen bonding helped drive proteins towards homochirality.

Abstract:

This thesis describes the synthesis of six bicyclic homochiral thiazolium salts for the catalysis of certain carbon-carbon bond formation reactions in an asymmetric manner. The synthesis of chiral thiazolium salts has been described in the literature previously. However, these catalysts gave either high chemical yields and low enantiomeric excess or low chemical yields and only moderate asymmetric induction in the carbon-carbon bond formation reaction. The synthesis of the rigid bicyclic thiazolium salts was attempted by the well-known α-haloketone route. This failed to yield the corresponding thiazolium salt because attempts to synthesise the α-haloketones of the bicyclo[2.2.1]heptane series gave only Wagner-Meerwein rearranged β-haloalcohols. The synthesis of the α-bromoketone of the bicyclo[2.2.2]octane series, however, was successful. Unfortunately, it did not react with thiocarbamates or thioformamide to give the desired thiazolium salts, probably due to steric congestion. Alternatively, thiazoles can be formed via the α-aminoketone route. The thiazoles were prepared in a three step synthesis, starting from bicyclic[2.2.2]octane silyl enol ethers in up to 35% yields. The silyl enol ethers were then converted into the α-ketooximes followed by reduction, formylation and thiocyclisation to give the desired thiazoles. The enantiomers of the thiazoles were separated by fractional recrystallisation of their diastereomeric salts with (R)- or (S)-camphorsulfonic acid. The homochiral thiazoles were then converted into the corresponding methyl and benzyl thiazolium salts. The catalysts were tested in the benzoin condensation to give benzoin, and in the dimerisation of butyraldehyde to produce butyroin. Benzoin was formed in up to 100% chemical yield and up to 25% e.e. For the first time, asymmetric induction was observed in the dimerisation of aliphatic aldehydes catalysed by thiazolium salts. Butyroin was formed in up to 70% chemical yield by only 8% e.e.

Abstract:

Chapter One introduces the principle of alkoxide and phosphine oxide as ligands for lanthanides and electropositive metals, ligand self-recognition, stereoselective polymerisation of lactide, fixation of CO2 and finally copolymerisation of CO2 and epoxide. Chapter Two shows the synthesis of the proligands rac-HLR (a racemic phosphine oxide-alkoxide, A, where R = tBu, Ph or C6H3-Me-3,5) and explores the resolution into diastereomeric RRR- and SSS-M(LR)3 to afford C3–symmetric M(LR)3 complexes, B (where M = Sc, Lu, Y, In, Bi or La). It also demonstrates that the process is under thermodynamic control and driven by ligand self-recognition via the synthesis of bis(LR) adducts (LR)2MX, C, (where M = Y or In and X = N(SiMe3)2 or OC6H3-tBu2-2,6) and mono(LR) adducts (LR)MX2, D (where M = Al or In and X = N(SiMe3)2, CH2SiMe3 or Me). Finally, it outlines the fixation of CO2 into an indiumamide bond. Chapter Three contains a detailed investigation of the potential of the MIII complexes as initiators for the stereoselective polymerisation of lactide, - caprolactone, glycolide and copolymerisation of lactide and -caprolactone, lactide and glycolide and CO2 and epoxide. Chapter Four investigates the use of rac-HLtBu in the resolution into diastereomeric RR- and SS-M(LtBu)2 complexes, E (where M = Ca, Zn or Sn), and of rac-HLPh into [M(LR)2]2 complexes, F (where M = Mg, Co or Sn and R = Ph or C6H3-Me-3,5) and mono-(LtBu) adducts (LtBu)MgX, G (X = N(SiMe3)2 or OC6H3-tBu2-2,6). It also describes the synthesis of protonated MII complexes (HLR)MCl2, H (where M = Mg, Zn or Sn and R = tBu or Ph). Finally, it details the polymerisation of lactide and its copolymerisation with glycolide using MII complexes as initiators. Chapter Five gives full experimental details and analytical data for the herein described novel compounds.
