The preparation of quinones from podophyllotoxin and peltatins of the aryltetrahydronaphthalene class by oxidative demethylation is described. The derivation of 2′-substituted ortho-quinones from these products by the reductive addition of azide, bromide, and chloride and subsequent oxidation by periodate is reported. Acid-catalysed reactions of ortho-quinones with alcohols are described including

From the rhizomes of american Podophyllum peltatum L. it was possible to isolate and characterize four lignan glucosides with anti-mitotic activity: podophyllotoxin-β-D-glucoside (IX), β-peltatin-β-D-glucoside (XI), 4′-demethylpodophyllotoxin-β-D-glucoside (X) and α-peltatin-β-u-glucoside (XII). The constitution of β-peltatin-β-D- glucoside was deduced from the fact that enzymatic cleavage with emulsin
