Fragmentierung von α,β‐Epoxy‐ketoximen zu Acetylenketonen. Vorläufige Mitteilung

Abstract
A new version of the oxidoketone‐alkynone fragmentation is described. Two steroidal α,β‐oxido‐oximes are shown to fragment to the corresponding alkynones when treated with hydroxylamine‐O‐sulfonic acid in alcaline solution at room temperature.
