Abstract
This work concerns the early evaluation of synthetic strategies towards the recently discovered natural product camporidine A, which displays a pronounced anti-metastatic activity. Three conceptually different strategies were evaluated including an imino Diels-Alder reaction, an aza-Michael/aldol sequence and an intramolecular [2+3] cycloaddition. With the final cycloaddition approach it was possible to synthesize the central bicyclic tetrahydropyridine containing core-structure of camporidine A. In the second part of this work the multi-gram scale synthesis and derivatization of 7,19-epoxysteroids, which display characteristic anti-metastatic properties, were performed. The 7,19-epoxysteroids were evaluated in the context of their potential for apoptosis induction on a series of cancer cell lines as well as their synergistic and resistance breaking effects on leukemia cells and some promising candidates were identified.
