1. Synthetic studies on naphthoxylosides - labeled compounds and mechanistic studies on acetals
Sammanfattning : Labeled analogs to an antiproliferative naphthoxyloside have been synthesized and evaluated. Our investigations have shown that the fluorescently labeled analogs are poor structural analogs, and the physical and biological properties are altered to a large extent. LÄS MER
2. Terpenoid Conidiation Factors in Penicillium cyclopium
Sammanfattning : Filamentous fungi produce asexual dispersive spores (conidia), when conditions are not suitable for apical extension growth. Conidiation (the process by which conidia produced) in genus Penicillium has attracted considerable interest because of its wide usage in different areas. LÄS MER
3. Synthesis of some acetals and glycosides
Sammanfattning : .... LÄS MER
4. Acetals - Exploring reactivity for improved carbohydrate synthesis
Sammanfattning : In my research, I have explored various aspects of acetals and their reactivity. Acetals have a central role in carbohydrate chemistry as an inherent functionality and as versatile protecting groups. The first part of the thesis summarizes results on regioselective reductive openings of benzylidene acetals. LÄS MER
5. Lewis acid promoted endocyclic cleavage of glycosides and related acetals
Sammanfattning : This thesis is a summary of five papers concerning endocyclic cleavage of glycosides and related acetals. Simple lactol ethers undergo endocyclic cleavage to give acyclic chain extended products on treatment with organoaluminium and organotitanium reagents. LÄS MER
