概要

Isousnic acid (IIIb), a structural isomer of usnic acid, was isolated from lichens of Cladonia spp. The so-called "Isodihydrousnic acid" obtained by the thermal rearrangement of dihydrousnic acid has been discussed in comparison with isodihydrousnic acid (XII) prepared by catalytic hydrogenation of isousnic acid.
