ACETAL-BEARING REARRANGED VIBSANE-TYPE DITERPENOIDS FROM VIBURNUM AWABUKI

摘要

Neovibsanin J(1),neovibsanin K(2),and neovibsanin P beta),unique vibsane-type diterpenoids bearing an acetal moiety at the C-7 position,were isolated from the leaves of Viburnum awabuki and their structures were elucidated by NMR spectral analysis using 2D techniques.
