Popis: | Includes bibliographical references. Novenamine, a known antibacterial agent, is composed of 3-0-carbamoyl noviose (novobiose) glycosidically linked to a 4-hydroxy-3-amino-coumarin unit. Its activity as a DNA-gyrase inhibitor and the absence of analogues containing 4-epi-noviose provided the rationale for developing new synthetic routes to these analogues. This thesis describes the total synthesis of the methyl glycosides of noviose and C-4-epi-noviose, methodology for the introduction of the C-3 carbamoyl group to both isomers, an alternative synthesis of the coumarin component, progress towards a C-5 analogue of 4-epi-noviose and a model study of methodology for the glycosidic coupling of the coumarin unit to suitably activated sugars. |
