Structural Reassignment of Cytosporolides A–C via Biomimetic Synthetic Studies and Reinterpretation of NMR Data

A structure revision for the recently isolated fungal meroterpenoids, cytosporolides A–C, is suggested based on biosynthetic speculation and reinterpretation of existing spectroscopic data. The structure revision is supported by a biomimetic synthetic study, featuring a [4 + 2] cycloaddition reaction between a presumed <i>o</i>-quinone methide intermediate and β-caryophyllene.
