The new lichen depsides, 2′-O-methylnorbarbatic acid (9) and 2′-O-methylnorobtusatic acid (12) have been detected in Pseudocyphellaria norvegica and the structures confirmed by total synthesis. In addition, the known depsides 4-O-demethylbarbatic

The crystal structure of 22α-hydroxystictan-3-one has been determined by X-ray diffraction. Rings A and B of this keto alcohol have been shown to adopt twist boat conformations. Despite the presence of the twist boat ring A system photochemical rear

The hopane triterpenoid in the extractives from P. mougeotiana, reported in Part VII1 of this series as hopane-6α,7α,22-triol, is now shown to be hopane-6α,7β,22-triol (1j). There is a consequential revision of the two triol diacetate structures

Chemical shift assignments are reported for some hopane triterpenoids variously oxygenated at C3, C6, C7, C15, C22 and/or C24. Substituent group effects are compared and correlated with a local symmetry axis. Revisions to a recently reported interpre

A complete assignment of the 1H and 13C n.m.r. signals of the lichen triterpenoid 12α-acetoxyfern-9(11)-en-3 β-ol (lb) has been achieved by using one- and two-dimensional n.m.r. techniques. Evidence in support of one of two recently advanced assign
