Cyclotrimerization approach to unnatural structural modifications of pancratistatin and other amaryllidaceae constituents - Synthesis and biological evaluation

The phenanthridone core of pancratistatin lacking all aromatic oxygenation was prepared by cyclotrimerization of acetylene-containing scaffolds 30 and 41, reflecting the natural and the C-1 epi configuration, respectively, of the amino inositol moiety. Th

Cyclotrimerization strategy toward analogues of amaryllidaceae constituents. Synthesis of deoxygenated pancratistatin core

(Chemical Equation Presented) A derivative of pancratistatin having no oxygenation in the aromatic ring was synthesized by a new strategy based on the cobalt-catalyzed cyclotrimerization of acetylenes as a prelude to diversity-oriented synthesis of furthe
