Über Steroide und Sexualhormone. (114. Mitteilung). Versuche zur Herstellung von 4, 13‐Dioxychrysen‐Derivaten

Abstract: Das oestrogen stark wirksame 1,2,10 ,Il-Tetrahydro-5,14-dioxy-chrysen3) tragt die funktionellen Gruppen an den beiden endstandigen Ringen des Chrysen-Geriistes in den Stellungen 5 und 14. Der gleichen Gruppe von Chrysen-Derivaten kann das D-Homo-dihydro-testosteron4), eines der kraftigsten Androgene, welches nach der beim Chrysen iiblichen Numerierung Sauerstoff -Funktionen in Stellung 4 und 14 besitzt, zugeordnet werden. Es erschicn deshalb von Interesse auch Verbindungen dieser Reihe mit Sauerstoffatomen in … Show more

“…The general method to prepare the final compounds 4a –z is outlined in Scheme 1. The oximes 2a – j (Table 1), required in the present work, have been obtained via reaction of the corresponding ketones 1a – j with hydroxylamine hydrochloride, as previously reported [3,7,8,9,10,11,12,13,14]. The two oxime geometric isomers were not separated, based on the previously reported absence of appreciable difference in β- blocking activity between the E- and Z- isomers of the final oxime ether derivatives [15].…”

“…All the ketones used were commercially available from Sigma-Aldrich Chemical Company (Munich, Germany), except benzophenone and acetophenone that were purchased from El-Nasr Pharmaceutical Chemicals Company, Cairo, Egypt. Oximes 2a – j were prepared following the procedures reported in the literature [3,7,8,9,10,11,12,13,14]. Two of the oxirane compounds 3i and 3j were previously reported in the literature [14].…”

“…The most frequently used procedure for the preparation of allophanates is the reaction of an alcohol with cyanic acid. Cyanuric acid is depolymerized to cyanic acid in a stream of carbon dioxide or nitrogen and passed into the alcohol (23,84,95,129,130,165,194,210,219) or into a solution of the alcohol in an inert solvent (108,222). Alternatively, the cyanic acid may be condensed (b.p.…”

“…Substituted aryl Grignard reagents have been used to prepare substituted phenylethanols. Thus, bromoanisoles (1,26,70,103,152,189), bromomethylanisoles (1, 26,189), bromophenetoles, bromotolyl butyl ether (26), phenoxybromobenzene (70), and m-(t rifluoromethyl)bromobenzene (197) have been converted into Grignard reagents and caused to react with ethylene oxide to produce the corresponding substituted phenylethanols.…”
