WebbOn the basis of this finding a series of chemically related phlegmacins (2-5), flavomannins (6-8), and rufoolivacins (9-11) isolated from several species of Cortinarius, a genus of higher fungi, and 5 synthetic vismione-like anthranoids (12-16) were evaluated as well. WebbThe structure of compound 1 was established on the basis of its spectroscopic data and the absolute configuration determined as P and 3’S by comparing the CD and ¹H NMR spectra of 1 with those of the phlegmacins 4 and 5. Compound 1 represents the first phlegmacin type pigment isolated from the ascomycete Agid: 5222678 the hunts charlwood
