Chemistry and Biological Activity of Vibsane-type Diterpenes

Vibsane-type diterpenes from Taiwanese Viburnum odoratissimum.

Two new eleven-membered and three new seven-membered vibsane-type diterpenes, named vibsanin L (1) and 14-hydroxyvibsanin F (2), and vibsanin I (3), 14R*,15-epoxyvibsanin C (4) and 14S*,15-epoxyvibsanin C (5) respectively, have been isolated from Viburnum odoratissimum collected in Taiwan. Their structures have been elucidated by spectroscopic analyses and comparison of Nuclear magnetic resonan...

Chemitsry and Biological Activities of Vibsane-type Diterpenoids

Abstract – This review focuses on the structural diversity, biological activities and synthesis of vibsane-type diterpenoids. Vibsane-type diterpenoids are considered to be rarely occurring natural products because they have been found exclusively in a few Viburnum species such as V. awabuki, V. odoratissimum, and V. suspensum. These diterpenoids are further classified into 11-membered ring, 7-...

Seven-membered vibsane-type diterpenes with a 5,10-cis relationship from Viburnum awabuki.

New five seven-membered vibsane-type diterpenes named 5-epi-vibsanin C, 5-epi-vibsanin H, 5-epi-vibsanin K, 18-O-methyl-5-epi-vibsanin K and 5-epi-vibsanin E have been isolated from the leaves of Viburnum awabuki (Caplifoliaceae). Their structures have been elucidated by analyses of spectroscopic data and comparison of their spectral data with those of the previously known seven-membered vibsan...
