Total syntheses of racemic fukinone and of natural (+)-hydroxyeremophilone.
Abstract
Stereospecific total syntheses of two ketones, (±)-fukinone (3) and (+)-hydroxyeremophilone (1), members of the non-isoprenoid eremophilane family of bicyclic sesquiterpenes, are described. The former synthesis begins with a cyclohexanone, which is annelated, and the latter with a bicyclic ketone of known absolute configuration.
