Allylsilane-Based Annulations. Direct Stereoselective Syntheses of (+/-)-Graveolide and (+/-)-Aromaticin

An allylsilane-based annulation was used to construct a functionalized perhydroazulene.The C(1), C(5), and C(10) stereocenters, characteristic of the helenanolides, were established using a reductive alkylation strategy.Stereoselective syntheses of the pseudoguaianolides graveolide and aromaticin were achieved.
