This thesis focuses on the construction of individual isomers of the R-CHF-CHF-CHF-R’ motif. The multi-vicinal fluorine motif is new in organic chemistry and therefore stereoselective methods giving rapid access to these motifs and with flexibility need to be explored. The research in the thesis succeeded in the preparation of (2S,3R,4S)-314 and (2S,3S,4R)-328. In Chapter 1, an overview of the impact of fluorine in organic molecules is given. Recent developments in asymmetric electrophilic and nucleophilic fluorination are described, as well as the preparation of multivicinal fluoroalkane motifs. Aldol reactions of either (R)- or (S)-N-(α-fluoropropyl)-2-oxazolidinones, mediated by TiCl 4 are reported in Chapter 2. Such aldol reactions gave rise to identical α-fluoro-β-hydroxy- aldol products with high diastereoselectivities (95% dr). After removal from the auxiliary α- fluoro-β-hydroxy- products were converted to the corresponding α,β-difluoro products. The synthesis of non symmetric vicinal trifluoro motifs (2S,3R,4S)-314 and (2S,3S,4R)-328 is described in Chapter 3. They were prepared by direct fluorination in three steps of the corresponding (2R,3R,4R)-erythro and (2R,3S,4S)-threo enantio-enriched epoxy-alcohols. The two erythro and threo epoxy-alcohol isomers behave very differently during the first fluorination step and then an attempt to study and rationalise this difference in behaviour is made.

The ability to discriminate between stereoisomers of a-tocopherol was studied in five patients with abetalipoproteinemia (ABL) because an impairment in secretion of apolipoprotein B-containing lipoproteins might impede the normally enhanced plasma transport of RRR-a-tocopherol. An oral dose containing 3.7 g of each 2R,4′R,8′R-α-[5-C2H3]tocopheryl acetate (d3RRR-α-tocopheryl acetate) and 2RS,4′RS,8′RS-α-[5,7-(C2H3),]tocopheryl acetate (d6all rac-α-tocopheryl acetate) was administered, then the labeled and unlabeled a-tocopherol contents of plasma and red blood cells from multiple blood samples obtained at selected times up to 72 h following the dose were quantitated. ABL plasma contained about 1%-10% of the d3-RRR-a-tocopherol concentrations of normal subjects given only 150 mg of each isotope. Three of the patients discriminated between forms of a-tocopherol with ratios of RRR-/allrac-α-tocopherol ≥ 1.8, similar to normals. These data suggest that the hepatic tocopherol binding protein is present and functional in ABL patients. Although two of the patients did not discriminate between stereoisomers of a-tocopherol, it is likely that this resulted from nearly a complete block in very low density lipoprotein (VLDL) secretion. Thus, the ability of ABL patients to absorb and transport orally administered vitamin E is markedly impaired and variable among patients.
