Abstract

Digitoxin (1) and digitoxigenin (2) react with sodium
nitroprusside [disodium-pentakis (cyano-C)-nitrosy1-ferrate(II)] under weakly basic conditions forming the
corresponding complexes 3 and 4, which were characterized
by elementary analysis and IR-spectra. 3 and 4
are cleaved by cyanide or carbon dioxide/dil. acetic acid
to the C-21-oximes 11 and 12, respectively.

Digitoxin (1) und Digitoxigenin (2) reagieren mit Nitroprussidnatrium[Dinatrium-pentakis(cyano-C)-nitrosylferrat(II)] unter schwach basischen Bedingungen unter
Bildung der entsprechenden Komplexe 3 und 4, welche
durch Elementaranalysen und IR-Spektren charakterisiert
wurden. 3 und 4 wurden durch Cyanid bzw.
Kohlendioxid/verd. Essigsäure zu den analogen C-21-
Oximen 11 und 12 abgebaut.
