Streszczenie:
The temporal degradation of the Belousov-Zhabotinskii substrates lactic acid, pyruvic acid, bromo- and dibromo pyruvic acid is investigated. The only final product of non-brominated substrates is acetic acid. From brominated educts only brominated acetic acids result. The concentrations of the stable products are determined as a function of time. The gross reactions are mainly based on simple consecutive first order reactions. For the pyruvic acid rate constants are determined.

Streszczenie:
A rapid PCB-screening protocol, based on a combination of extraction techniques and instrumental nuclear activation analysis (INAA), required water soluble brominated internal standard that undergoes facile hydrolysis to a lipophilic brominated counterpart. Bromophenyl glucuronic acids 2, 3, 7 were synthesized for this application. Glucuronic acids 2 and 3 were prepared by bromination of phenyl β-D-glucopyranosiduronic acid in 81 and 54%, respectively, whereas compound 7 was prepared by coupling methyl 2,3,4-tri-O-acetyl-α-D-glucopyranosyluronate bromide (5) with 2,4,6-tribromophenol. Incubation with β-glucuronidase indicated that tribromophenyl derivative 7 is an excellent substrate, with near quantitative conversion to tribromophenol within seconds of incubation with the enzyme.

Streszczenie:
An investigation of the dichioromethane extract of the sponge, Xestospongia testudinaria indicated that the extract was composed of approximately 40% sterols, 30% saturated fatty acids, 10% mono-unsaturated fatty acids and 20% poly-unsaturated acids. The sterol profile was found to vary between two collections of the sponge. In the first collection the major sterol was the C30 compound, xestosterol (4), which had not previously been reported to occur in this species. In the second collection there was a wider distribution of components with cholesterol (2a) being a major constituent and xestosterol being present in a much lower percentage than in the first collection. The poly-unsaturated acid fraction contained an extremely complex mixture. The novel brominated bisacetylenic C18 (47) and brominated C28 (65) acids were found to be the major components. Another six novel brominated acetylenic acids, which were very unstable, were also identified as well as an ester of 4 with 47. The method developed for the separation of the poly-unsaturated acids from the other classes of metabolites and for the isolation of the pure compounds is discussed and their structural elucidation, largely on the basis of NIMR spectroscopy is described. From the hexane extract of Carteriospongia foliascens, two novel bisalkylated norscalarane derivatives (114 and 116) and a bisalkylated scalarane derivative (130) have been isolated. By use of high field NMR and multipulse NMR techniques a complete assignment of the 111 and 13C NMR spectra of 130 has been achieved on 1.5mg of material. This represents the first report of a complete assignment of the 1J4 NMR spectrum of a scalarane derivative. The C-4 stereochemistry of 130 was determined by use of 1H NMR spectroscopic techniques, which gave results in agreement with the previously used 13C NMR method.

Streszczenie:
Humans are exposed to persistent organic pollutants (POPs) such as brominated flame retardants (BFRs, specifically polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecane (HBCD)) and perfluoroalkyl acids (PFAAs, specifically perfluoroalkane sulfonate (PFOS) and perfluorooctanoic acid (PFOA)). They are used in consumer products found in cars, offices, homes and day care centers. Diet was earlier thought to be a major human exposure route for legacy POPs, but does not account for body burdens found for many new POPs and indoor exposure from air and dust has been hypothesized as also important. In this thesis, BFRs in air and dust, and PFAAs in dust from different indoor microenvironments in Sweden were analysed, and the results used to estimate human exposure. BFRs and PFAAs were detected in dust from all microenvironments and PBDEs in all air samples. BFR and PFAA exposure occurs mostly in peoples’ homes with toddlers having higher intakes from dust ingestion than adults. Inhalation and dust ingestion play minor roles compared to diet for humans with median exposures, but in worst case scenarios, dust ingestion may be significant for a small part of the Swedish population. Sampling using home vacuum cleaner bag dust and researcher-collected above floor dust was compared. Correlations were seen for ∑OctaBDE and ∑DecaBDE but not for ∑PentaBDE and HBCD. Higher PBDE concentrations were found in above floor dust but higher HBCD concentrations were found in vacuum cleaner bag dust. BDE-47 concentrations were correlated between vacuum cleaner bag dust and breast milk, indicating exposure through dust ingestion. Similar concentrations of PBDEs were measured in indoor and outgoing air from day care centers, apartment and office buildings. Indoor air explained 54-92% of ∑PentaBDE and 24-86% of BDE-209 total emissions to outdoor air in Sweden, supporting the hypothesis that the indoor environment is polluting ambient air via ventilation systems.

At the time of the doctoral defense, the following papers were unpublished and had a status as follows: Paper 2: Accepted. Paper 3: Accepted. Paper 4: Manuscript.

Streszczenie:
The tetracyclic alkaloid (–)-dendrobine 3 has at its core a cyclohexane that is substituted at each of its six positions, including one quaternary center. Erick M. Carreira of ETH Zürich chose (Angew. Chem. Int. Ed. 2012, 51, 3436) to assemble this ring by the Ireland-Claisen rearrangement of the lactone 1. The absolute configuration of the final product stemmed from the commercial enantiomerically pure acetonide 4, which was selectively converted to the Z-ester 5. Following the precedent of Costa, TBAF-mediated conjugate addition of 2-nitropropane to 5 proceeded with high diastereocontrol, to give, after free radical reduction, the ester 6, which was carried on the aldehyde 7. Exposure of the alkyne 9 to an in situ-generated Schwartz reagent followed by iodination gave 10 with 10:1 regioselectivity. It was possible to separate 10 from its regioisomer by careful silica gel chromatography. Metalation followed by the addition to 7 gave an intermediate that was conveniently debenzoylated with excess ethyl magnesium bromide to deliver the diol 11. Selective oxidation led to the lactone 1. Exposure of 1 to LDA and TMS-Cl induced rearrangement to the cyclohexene acid, which was esterified to give 2. Deprotection and oxidation then gave the enone 12. Cyclohexene construction by tethered Claisen rearrangement is a powerful transformation that has been little used in target-directed synthesis. Selective addition of pyrrolidine to the aldehyde of 12 generated an enamine, leading to an intramolecular Michael addition to the enone. This selectively gave the cis ring fusion, as expected, but the product was a mixture of epimers at the other newly formed stereogenic center. This difficulty was overcome by forming the enamine from N-methylbenzylamine. After cyclization, hydrogenation set the additional center with the expected clean stereocontrol, and also effected debenzylation to give 14. To close the last ring, the ketone 14 was brominated with the reagent 15, which was developed (Can. J. Chem. 1969, 47, 706) for the kinetic bromination of ketones. Exposure of the crude α-bromo ketone to 4-dimethylaminopyridine then effected cyclization to 16. Following the literature precedent, reduction of the ketone of 16 with NaBH4 followed by gentle warming led to (–)-dendrobine 3.
