RO-'" OR drolysis of actinospectacin with hot 6 N hydrochloric acid gives a crystalline fragment, actinamine dihydrochloride C8HdS204. 2HCl. The free base, actinamine OR CeH1pN, O4* 1/2H:! O, is readily obtained from its di- I. R= R'= H hydrochloride by ion exchange. In the following discussion we present chemical evidence for the st'ructure and stereochemistry of actinamine (I).
