Enantioselective Total Syntheses of Quinolizidine Lycopodium Alkaloid Cermizine D and Cytotoxic Marine Macrolide Mandelalide A

Creator:

Veerasamy, Nagarathanam

Abstract:

The enantioselective total synthesis of quinolizidine-containing natural product cermizine D and formal syntheses of senepodine G and cermizine C has been achieved. These natural products are members of the lycopodium alkaloids, which have attracted significant attention due to their exciting biological activities and the diverse structural scaffolds. Key steps in...

Computational Investigation and Prediction of Mechanisms and Stereocontrol in Complex Organic Reactions

Creator:

Pattawong, Ommidala

Abstract:

Complex organic transformations, such as the addition of pyrrole to ketene using planar chiral organocatalyst (*PPY), the four-component anhydride- Manniach reactions, and the site-selective desymmetrization of meso-1,2-diol, are remarkable synthetic reactions that provide high yield and high selectivity. However, the exact mechanism and origins of stereocontrol for theses synthetic organic...

Synthetic studies toward the total synthesis of azaspiracid-1

Creator:

Su, Dong

Abstract:

Azaspiracid-1, a novel marine toxin that contains 9 rings and 20 stereogenic centers, has drawn considerable attention from synthetic groups worldwide due to its structural complexity, which includes a unique trioxabisspiroketal fused to a tetrahydrofuran ring (ABCD rings), a piperidine-tetrahydrofuran spiroaminal system fused to a 2,9-dioxabicyclo[3.3.1]nonane system (FGHI rings), a...
