Phenalenones

WebThe plant and fungal phenalenones are structurally quite different and are derived from unrelated biosynthetic pathways. Different numbering systems have traditionally been used for the two classes of compounds and we have retained this dichotomy in the present review. Keywords Dimethyl Ether Absolute Configuration Methyl Ether Colouring Matter WebAmong these, phenalenones are a class of hexa- or heptaketides bearing a perinaphtenone-type tricyclic system . As summarized in a recent comprehensive review, these compounds can have immense structural variations, such as homo- and heterodimerization, the incorporation of additional carbon frameworks, and a high degree of oxygenation and ...
