Significance

Baran and co-workers previously postulated the biosynthetic origins of the chartellines (P. S. Baran et al. Angew. Chem. Int. Ed. 2005, 44, 3714-3717), and have now disclosed a bio-inspired approach to (±)-chartelline C, the scarcest member of the group. Noteworthy in this synthesis is a remarkable four-step, one-pot cascade sequence that affords the spiro-β-lactam system characteristic of the chartellines.
