Rhodomyrtals A–D, four unusual phloroglucinol-sesquiterpene adducts from Rhodomyrtus psidioides

Abstract

Four unusual phloroglucinol-sesquiterpene adducts, rhodomyrtals A–D (<bold>1–4</bold>), representing two unprecendented carbon frameworks of phloroglucinol coupled eudesmane with the linkage at C-12′, were isolated from<italic>Rhodomyrtus psidioides</italic>.
