P-Alectoronic acid

Methylphysodone (117) was isolated from Pseudevernia fur-furacea (339). 3-Alectoronic acid (118) and P-collatolic acid (119) are diphenyl ethers from Asahinea chrysantha (476) and A. scholanderi (476, 672) and exhibit an equilibrium between the keto-acid and lactol tautomers. 2" -0-Ethyl-P-alectoronic acid (120) from Alectoria sarmen-tosa (327) is probably an artefact formed during extraction by reaction of P-alectoronic acid with ethanol. [Pg.80]
