Corsifurans A-C, 2-arylbenzofurans of presumed stilbenoid origin from Corsinia coriandrina (Hepaticae).
Chemical investigation of the diethyl ether extract from the liverwort Corsinia coriandrina resulted in the isolation of a new 2-arylbenzofuran compound called corsifuran A. The structure was identified by spectroscopic techniques and confirmed by synthesis. Two minor constituents of similar structure, and two related stilbenoids and a bibenzyl were identified by comparison of the mass spectra and GC retention indices with authentic samples. Due to the similarity in substitution patterns a stilbenoid origin of the corsifurans is proposed.
