note = "Funding Information: Conyzorigun must therefore have structure (1). OMe Me0 (11 (2) To our knowledge such a highly oxygenated aromatic compound with a reasonably stable keten acetal system is without precedent in extractives from plants. However we feel conyzorigun is biogenetically related to the chromens which are abundant in the plant. We thank the University of Ibadan for a Senate Research grant, the University of Liverpool for the 13C n.m.r. spec- trum, and Mr. G. A. Adesida for collecting plant materials.
