Die vorliegende Erfindung betrifft den in den Ansprüchen gekennzeichneten Gegenstand.
Die Umsetzung wird vorzugsweise bei Raumtemperatur
durchgeführt.
Es ist besonders wichtig, daß die beanspruchte Umsetzung von Vinylketonen zu Verbindungen der
Formel Il in Abwesenheit einer Base erfolgt, da in Gegenwart von Basen Enolisierung der fCetogruppen
am Ring stattfindet und überbrückte Ketole gebildet werden. So führt z. B. die Umsetzung von 2-Methylcyclopentan-13-dion
mit Methylvinylketon in entsalztem O u
die ein bevorzugtes Ausgangsmaterial zur Herstellung von Steroiden ist
In früheren Veröffentlichungen [z. B. P. Wieland und
K. Miescher, HeIv. Chim. Acta. 33,2215 (1950) und CRC
Boyce und ]S. Whitehurst, J. Chem. Soc 2022 (1959)]
wurde die Verbindung der Formel IU irrtümlich als Reaktionsprodukt von 2-Methylcyclopentar,-13-dion
und Methylvinylketon in Gegenwart einer Base bezeichnet Die Verbindung der Formel III isi jedoch ein
öl, dessen Struktur durch NMR-Spektren eindeutig gesichert ist während die früher beschriebene Verbindung
ein kristsUiner Feststoff ist mit einer Bands im
IR-Spektrum bei 3,1 μ. Die Verbindung der Formel IH
zeigt jedoch erwartungsgemäß eine solche Bande bei 3,1 μ nicht
Zu einer Suspension von 65 g 2-Methyl-l,3-cyclopentandion
in 135 ml entsalztem Wasser wurden 96 ml Methylvinylketon gegeben. Das Gemisch wurde 5 Tage
unter Stickstoff bei 20" gerührt und nach Filtration mit 200 ml Benzol geschüttelt Durch Zusatz von Natriumchlorid
wurde eine Phasentrennung erreicht Die wäßrige Phase wurde zweimal mit 100 ml Benzol
extrahiert und die vereinigten organischen Phasen wurden mit Wasser und gesättigter Kochsalzlösung
gewaschen, über Natriumsulfat getrocknet und 1 '/2 Stunden mit Aktivkohle und Magnesiumsulfat gerührt
Nach Filtration wurde der Filterkuchen mit 100 ml heißem Benzol gewaschen. Die benzolischen Phasen
wurden im Vakuum eingeengt und ergaben 1003 g (95,6%) eines Rohprodukts, das nach fraktionierter
Destillation bei einem Druck von 0,08 bis 0,1 mm Quecksilber 92£5 g (87,6%) reines 2-Methyl-2-(3oxobutyl
>13-cyck>pentandion,
Kp. 100-1090C, in Form eines gelben Öls lieferte.
Ein Gemisch aus 10 ml Äthyl vinylketon, 88 mg Hydrochinon-monomethyläther, 11,2 g 2-Methyl-13-cycloDentandion,
0,08 ml Eisessig und 26 ml entsalztem Wasser wurde 15 Tage unter Argon bei Raumtemperatur
gerührt, nachdem am 4. Tag 9 ml und am 9. Tag noch einmal 9,5 ml Äthylvinylketon hinzugegeben worden
waren. Das Reaktionsgemisch wurcv i mit 50 ml Benzol
geschüttelt und die entstandene Emulsion bis zur Sättigung der wäßrigen Phase mit festem Natriumchlorid
versetzt Die wäßrige Phase wur: e mit 50 ml Benzol extrahiert Die vereinigten Benzole «trakte wurden mit
einem Gemisch von Natriumsulfat Magnesiumsulfat und Aktivkohle behandelt und unter vermindertem
Druck eingeengt Es wurden 21,1 g csnes Öles erhalten,
das unter einem Druck von 0,05 mm Quecksilber fraktioniert destilliert wurde. Die bei 105-118°
siedende Fraktion (17,47 g -89%) wuide nochmals unter einem Druck von 0,025 mm Quecksilber destilliert
und lieferte 16 g (834%) 2-Methyl-2-(3-oxopentyl)-U-cyclopentandion,
Kp.0,025 97 -115".
