Abstract

The structure of the natural coumarins, 5-methoxyseselin 7 and trachyphyllin 14 have been confirmed by total syntheses from 7-acetoxy-5-prenyloxycoumarin 1 in good overall yields. Convenient synthetic routes to the natural coumarins, coumurrayin 4 and xanthoxyletin 10 have also been established.
