dc.description.abstractThe isolation and structural determination of the lichen metabolites dechlorodiploicin (2), dechloro-O-methyldiploicin (3), buellolide (4), and canesolide (6) are described; buellolide (4) and canesolide (6) are thought to arise by catabolism of their congeneric depsidones, in the latter case with Smiles rearrangement.en
dc.description.sponsorship170-173 OC, was supported by its spectroscopic properties. That it is a phthalide was indicated by its i.r., vmax (CCI,) 1781 cm-l, and lH n.m.r. spectra (8 5.23, 2H, s). The high resolution mass spectrum, in addition to establishing the molecular formula, exhibited peaks at wz/e 219 (base)/221/223 attributed to the ion (11). Hydrogenolysis of buellolide (4) gave the diaryl ether (5), which like buellolide (a), exhibited a high field aromatic proton signal (8 6-00) in its J.C.S. CHEM.COMM.,1978 lH n.m.r.en
