Abstract

The leaves of Flueggea microcarpa contain the ethyl ester of brevifolin carboxylic acid. The elucidation of the structure of this isocoumarin involved extensive use of 1H and 13C NMR data, which are fully reported and analysed for the first time; especially useful were long-range CH coupling interactions. NMR parameters for some models, including norbergenin, as well as pyrogallol, gallic acid and their triacetates, are also reported.
