RESEARCH PRODUCT

Zur Chemie des Ecdysons, IV: Farbreaktionen von gesättigten und ungesättigten Steroidketonen

subject

Inorganic Chemistry Chemistry Stereochemistry

description

Die Farbreaktionen von Steroidketonen— besonders von Δ9(11)-12-Ketonen, Δ7-6-Ketonen, Δ4-3-Ketonen und Δ5(6)-7-Ketonen — mit m-Dinitrobenzol (Zimmermann-Reagenz), 2.4-Dinitro-phenylhydrazin und Triphenyltetrazo-liumchlorid werden untersucht. Die Kombination der Farbtests gibt eine schnelle Moglichkeit, die Lage einer Ketogruppe im Steroidgerust zu bestimmen oder einzuengen. Im Fall des Ecdysons konnte von drei moglichen Ketonen die Δ4-3-Keton-Struktur ausgeschlossen werden.
