Abstract
A new synthesis of 2,2-dimethyl-12-[3-methylbut-2-enyl]-2H,6H-pyrano[3,2-b]xanthen-6-one (7) is described from 1,3-dihydroxyxanthone and involved the preparation of a linear dihydropyranoxanthone (26), its conversion into the pyranoxanthone (14) and its prenylated derivative (31) followed by a Claisen rearragement leading to the target substrate (7).
