The synthesis of 4-oxypterosin E (6), a phenolic indanone norsesquiterpene, is described.The synthesis starts from an ester-ether derivative (9) of the known 3-hydroxy-2,6-dimethyl-1-phenylacetic acid (8) and involves formylation, Horner reaction, hydrolysis, hydrogenation, cyclodehydration and demethylation in succession, as depicted by the sequence 9 -> 10 -> 11 -> 12 -> 13 -> 14 -> 6.
