Digitalose

Digitalose is a deoxy sugar that is a component of various cardiac glycosides including thevetin and emicymarin. It was first reported in 1892 as being obtained by the hydrolysis of Digtalinum verum.[1][2] The chemical structure was first elucidated in 1943 by the German chemist Otto Schmidt.[3] Chemically, it is a methyl ether of D-fucose.
