Chemistry and Pharmacology
Summary Open column, high-performance liquid, and gas-liquid chromatographic procedures have been developed for the purification of synthetic warburganal intermediates (II–V) and drimenin (VI). The usefulness of thinlayer chromatography in revealing an obscured, unwanted product (VI) instead of a desired warburganal intermediate (V) is discussed. The relative stereochemical configuration of IV was confirmed by X-ray analysis.
