The yellow toxins produced by Cercospora Beticola. Part VIII : Chemical equilibrium between beticolins ; structures of minor compounds : beticolin 6 and beticolin 8

Abstract a general chemical transformation of the “linear” beticolin skeleton (beticolin 2 and 4) into a “bent” beticolin skeleton (cebetin A and beticolin 3 respectively) is described. Beticolins 6 and 8, minor components of mycelial extract are also characterized as minor compounds resulting from these transformations.
