Journal ArticleDOI
Reaktionen von Steroid‐Hypojoditen II. Über die Herstellung 18‐oxygenierter Pregnanverbindungen. Über Steroide, 187. Mitteilung
TL;DR: In this article, the reactions of 20-hydroxypregnanes with iodine and lead tetraacetate, mercuric or silver acetate yield the corresponding oxy radicals, and with the latter two reagents, 20-hypoiodites are definitely intermediates.
Journal ArticleDOI
Gewinnung von 1;4-Bisdehydro-3-oxo-steroiden. Über Steroide, 139. Mitteilung
TL;DR: In this article, a method was described which enables the production in only one chemical step of 1,4-bisdehydro-3-oxo-steroids inter alia from 3-oxO- steroids saturated in ring A or from α β-mono-unsaturated 3-ketones.
Journal ArticleDOI
New substitution reactions in steroids
TL;DR: It is shown that 20-hydroxy-18-C-radicals combine with iodine atoms, to give 18-iodides which can befurther substituted through radicals to give potential 18-oxo-compounds in high yield.
