Abstract

7-Hydroxypleurocorine (1), a novel spermidine alkaloid was isolated from the leaves of Pleurostylia opposita and its structure was elucidated by means of extensive 1H and 13C nmr studies involving DQF COSY, HOHAHA, HMBC and HMQC experiments. The relative stereochemistry of the molecule was also probed using NOE difference spectroscopy. 7-Hydroxypleurocorine represents a new type of spermidine derivative including a pyrrolidinone.
