Polyoxygenated cyclohexene derivatives from Uvaria rufa

Four new polyoxygenated cyclohexene derivatives, uvarirufone A (1) and uvarirufols A-C (2-4), along with ten related known compounds, were isolated from the EtOH extract of the aerial parts of Uvaria rufa BL. Their structures and absolute configurations were determined by in-depth spectroscopic and spectrometric methods in combination with molecular modeling.
