Connecting C19 norditerpenoids to C20 diterpenes: Total syntheses of 6-Hydroxy-5,6-dehydrosugiol, 6-Hydroxysugiol, and taiwaniaquinone H, and formal synthesis of dichroanone

Oxidation of the B-ring of abietane derivatives by Sharpless dihydroxylation gave the natural products 6-hydroxy-5,6-dehydrosugiol and 6-hydroxysugiol. Moreover, further oxidation gave a hydroxy dione derivative that provides a synthetic entry into the Ctaiwaniaquinoid family of natural products. This route is based on biosynthetic considerations and involves a benzilic acid rearrangement followed by decarboxylation. On the basis of this approach, a total synthesis of (-)-taiwaniaquinone H and a formal synthesis of (-)-dichroanone have been achieved. Georg Thieme Verlag Stuttgart - New York.

New strategy toward the diverted synthesis of oxidized abietane diterpenes via oxidation of 6,7-dehydroferruginol methyl ether with dimethyldioxirane

A series of oxidized abietane diterpenes have been synthesized from 8,11,13-abietanotriene. The reaction of 6,7-dehydroferruginol methyl ether with dimethyldioxirane (DMDO) was carried out under various conditions. In all cases, the oxidation of positions

Synthesis of C-7 oxidized abietane diterpenes from racemic ferruginyl methyl ether

A series of naturally occurring C-7 oxidized abietane diterpenes have been synthesized from racemic ferruginyl methyl ether in high yields. 6-Hydroxyl-5,6-dehydrosugiol (7) can be converted into stable xanthoperol (12) using high temperature. Among the products, the structures of sugiyl methyl ether (2) and 6(-hydroxysugiyl methyl ether (8) were determined by X-ray analysis.

New dimeric monoterpenes and dimeric diterpenes from the heartwood of Chamaecyparis obtusa var. formosana

Two dimeric monoterpenes obtusal A and B, and two dimeric diterpenes obtusanol A and B, along with (-)-(S)-citronellol, (-)-(S)-citronellic acid, (+)-borneol, (+)-sugiol, and (-)-6,12-dihydroxyabieta-5,8,11,13-tetraen-7-one, have been isolated from the heartwood of Chamaecyparis obtusa var. formosana and were characterized by spectroscopic means, including 2D-NMR techniques and chemical methods. Synthesis of(-)-obtusal A and (+)-obtusal B were carried out.
