Abstract
Part I. The synthesis of homochiral 2-methyl-1-azoniatricyclo (4.4.3.0$\sp{1,6}$) tridecane and 2-methyl-1-azonia-tricyclo (4.4.4.0$\sp{1,6}$) tetradecane salts 6 and 7 starting from L-glutamic acid and L-alanine respectively and their applications in phase-transfer catalysis are described. The application of these salts in the enantioselective phase-transfer catalyzed cyclopropanation reaction between diethyl bromomalonate and methyl vinyl ketone, 2-chloroacrylonitrile or acrolein gave products in good chemical yields, but the enantiomeric excess of the products was very low. Alkylation reactions with ethyl 2-oxocyclopentanecarboxylate or ethyl 2-oxocyclohexanecarboxylate and allyl bromide proceed to give products in good yields but with very low enantiomeric excess. Possible reasons for these results are discussed. Part II. The synthesis of some N-($\omega$-carboxyalkyl)lactams and N-($\omega$-carbethoxyalkyl)lactams and their pyrolysis over soda lime to give enamines are described. This investigation took place as part of a general investigation of the effectiveness of this carbon-carbon bond forming reaction in the synthesis of enamines and iminium salts and the ability to utilize this method in the synthesis of 1-azapropellanes with different ring sizes.Dept. of Chemistry and Biochemistry.
