Abstract

The aerial parts of Halfordia kendack (Rutaceae) have yielded a new furanocoumarin derivative which has been identified as 3,5-dimethoxy-3-(1,1-dimethylprop-2-enyl)-3,4-dihydropsoralen-4-one on the basis of spectroscopic and X-ray examination. This new compound, present in high concentration, is probably formed from a 4-O-prenylated precursor furanocoumarin via a Claisen rearrangement. No trace of the putative precursor was found in this sample.
