concise and divergent strategy for the synthesis of the naphterpin and marinone meroterpenoid families has been developed. The approach features a succession of pericyclic reactions—an aromatic Claisen rearrangement, a retro-6π-electrocyclization, and two Diels–Alder reactions—which facilitated the first totalsynthesis of naphterpin itself in five steps from 2,5-dimethoxyphenol, alongside similar

Trialkylsilyl ethers of 1,1-dioxygenated butadienes, substituted at position 3 by electron releasing substituents, undergo thermal rearrangement with 1,5-migration of the silylgroupfromoxygen to carbon.
