Synthetic Studies on Heterocyclic Natural Products

Speaker: Dr. Marco Ciufolini;Department of Chemistry, University of British Columbia, Vancouver, BC V6T 1Z1, Canada

Time/Place: Thursday, May 3rd at 3:00 pm, 130 SMed

Abstract: This presentation highlights recent efforts focusing on the total synthesis of biologically relevant nitrogenous natural products. Each target molecule poses chemical problems that serve as ideal vehicles for the development and application of new synthetic technology. Compounds of current interest include (i) thiopeptide antibiotics (genetic modulators and inhibitors of protein synthesis); (ii) polyoxazole natural products such telomestatin (potent and selective inhibitor of human telomerase); (iii) substances incorporating medium-ring nitrogen heterocycles or surrogates thereof such as mitomycinoids (antitumor agents); and (iv) spirocyclic alkaloids (immunusuppressants; cytotoxic agents; ion-channel blockers). The methodology aspects of each project will be discussed with an emphasis on transformations that rely on the use of hypervalent iodine reagents.
