Abstract

IN view of the recent communication on this topic by Cram1 to the editor of the Journal of the American Chemical Society, we wish to record that in the course of an extensive investigation on the chemistry of citrinin initiated in these laboratories in 1945, the synthesis of 4-methyl-5-ethylresorcinol2, m.p. of anhydrous material 94–95°, was effected in 1946, and the orientations of the two isomeric phenols ‘A' and ‘B' C11H16O3 afterwards established. From these results, inter alia, together with a study of the degradation products of methylated citrinin and of dihydrocitrinin and its ether, evidence has accumulated which leads to the conclusion that citrinin in all probability is best represented by the expression (II).
