| Abstract: | Partial demethylation of isopimpinellin and methylation of psoralene hydroquinone afforded 5-methoxy-9-hydroxypsoralene. The corresponding 5-isoprenyloxy derivative was used in the synthesis of cnidilin and its epoxy and glycol derivatives, which are all biogenetically feasible; the fatter two having as yet not been isolated from natural sources. |
