title: New Cleavage Methods for Cardiac Glycosides having a Doubly Linked Sugar1.
abstract: New cleavage methods for cardiac glycosides having a doubly linked sugar are described. Treatment with pyridine, alumina, or phenylhydrazine gave the desired genin in reasonable yield. The reaction products were separated and determined by high-performance liquid chromatography. The mechanism of the cleavage reaction has also been discussed.
