Rearranged vibsane-type diterpenes from Viburnum awabuki and photochemical reaction of vibsanin B

, : Rearranged vibsane-type diterpenes from Viburnum awabuki and photochemical reaction of vibsanin B. Chemical & Pharmaceutical Bulletin 53(1): 72-80

Nine new diterpenes, neovibsanin D (1), 7-epi-neovibsanin D (2),15-O-methylneovibsanin F (3),14-epi-15-O-methylneovibsanin F (4), 15-O-methyl-18-oxoneovibsanin F (5), 2-O-methylneovibsanin H (6), 2-0-methylneovibsanin I (7), neovibsanin G (8), and 14-epi-neovibsanin G (9), were isolated from a methanol extract of the leaves of Viburnum awabuki.
