the synthesis of optically active labdane-type diterpenes from (+)-manool 8 is described. We prepared the natural labdane-type diterpene 5 via key intermediate peroxide 9, and synthetic hydroxybutenolides 6 and 7 via a furan photosensitised oxygenation reaction of labdafuran (14). Compounds 5, 6, 7 and 9 were evaluated as inhibitors of the β-haematin formation and globin proteolysis, and then were
