Morphothebaine dimethyl ether

By the degradation of morphothebaine to 3 4 6 8-tetramethoxy-phenanthrene the position of all the substituents in the phenanthrene skeleton was revealed, and the structure of the base [n] was finally confirmed by the following synthesis of the dimethyl ether. [Pg.316]

Demethylation of morphothebaine can be effected by heating with dilute hydrobromic acid at 170° C., the product being 6-hydroxyapo-morphine, which reduces silver nitrate very rapidly and is oxidized by atmospheric oxygen even more readily than apomorphine [16]. Morphothebaine and its dimethyl ether give dark green amorphous substances on oxidation with alcoholic iodine [5],... [Pg.317]
