Make it simple: The separation of framework‐decorating from framework‐constructing steps facilitated the selective introduction of one prenyl group next to allyl groups. The selective epoxidation of the more electron‐rich prenyl group led to the efficient formation of the tetrahydrofuran moiety in the title compounds. Spectroscopic analysis of hyperibone I and comparison with literature data led to a revision of the original structure.
Macht es einfach: Die Trennung gerüstaufbauender und gerüstdiversifizierender Schritte ermöglicht die selektive Einführung einer Prenyl‐ neben Allylgruppen, und durch selektive Epoxidierung der elektronenreicheren Prenylgruppe wird das Tetrahydrofuranmotiv der Titelverbindungen gebildet. Spektroskopische Analysen und Vergleiche mit den Literaturdaten führten zur Bestätigung der revidierten Hyperibon‐I‐Originalstruktur.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
