Fosbergenone: 3-[2-(1,2,5,5-Tetramethyl-7-oxo-1,2,3,4,4<i>a</i>,5,6,7-octahydronaphthalen-1-yl)ethyl]-2,5-dihydrofuran-2-one

Abstract

A new ent-halimane diterpenoid, fosbergenone (1) was isolated from the foliar bud exudate of Gardenia fosbergii. The structure of 1 was elucidated based on spectroscopic data including IR, 1D and 2D NMR, as well as high-resolution mass spectrometry.
