Significance
Auripyrones A and B were isolated from a sea hare and exhibit cytotoxicity against HeLaS3 cells with the δ-pyrone functional group thought to be important for activity. Auripyrone A has been previously synthesized using a spiroacetalization approach (Angew. Chem. Int. Ed. 2006, 45, 2560), but the absolute configuration of auripyrone B was unknown.
