Nach dem Trocknen und Abziehen des Solvens bleiben 3,4 g (+)-3-Chinuclidinylmethanol-Borankomplex als helles Öl zurück. 5.6 g of (+) - 3-quinuclidinylmethanol hydrochloride, 1.32 g Sodium borohydride and 100 ml of tetrahydrofuran are over Night stirred. From the filtrate, the solvent is withdrawn, the residue was taken up in ethyl acetate and the solution obtained with saturated sodium chloride solution washed. After drying and removal of the solvent remain 3.4 g of (+) - 3-quinuclidinylmethanol borane complex back as light oil.
3,4 g des Borankomplexes werden in 100 ml Tetrahydrofuran 30 Minuten mit 2,63 g 60%igem Natriumhydrid bei Raumtemperatur gerührt, anschließend mit 4,89 g 80%igem Propargylbromid umgesetzt und 6 weitere Stunden gerührt. Das Reaktionsgemisch wird mit Alkohol vorsichtig zersetzt, das Solvens abgezogen, der Rückstand in 150 ml Essigester aufgenommen, die Lösung mit gesättigter Kochsalzlösung gewaschen und das Solvens erneut abgezogen. Zur Zerstörung der Boranschutzgruppe nimmt man den Rückstand in 50 ml Aceton auf und rührt mit 20 ml 3N-HCL über Nacht. Nach dem Abdampfen des Acetons wird die wäßrige Phase mit Essigester gewaschen, mit Pottasche alkalisch gestellt und mit Essigester extrahiert. Der Extraktionsrückstand wird an Kieselgel mit Essigester : Methanol : NH₃= 85 : 15 : 1 als Eluens flashchromatographiert und ergibt 4,3 g Propargylether, der in Alkohol mit der berechneten Menge Fumarsäure in das Fumarsalz übergeführt wird, das aus Alkohol-Ether umgefällt wird und in 3,9 g Ausbeute mit Fp. 132-133°C und =+28,47° (c=1, Methanol) anfällt.3.4 g of the borane complex are dissolved in 100 ml Tetrahydrofuran for 30 minutes with 2.63 g of 60% strength Sodium hydride stirred at room temperature, then reacted with 4.89 g of 80% propargyl bromide and 6 stirred for another few hours. The reaction mixture is with Alcohol carefully decomposed, the solvent withdrawn, the Residue taken up in 150 ml of ethyl acetate, the solution washed with saturated saline and the Solvens withdrew again. To destroy the Borane protective group takes the residue in 50 ml Acetone and stirred with 20 ml of 3N-HCl overnight. To The evaporation of the acetone, the aqueous phase with Washed ethyl acetate, made alkaline with potash and extracted with ethyl acetate. The extraction residue is on silica gel with ethyl acetate: methanol: NH₃ = 85: 15: 1 as Eluens flash chromatographed and gives 4.3 g of propargyl ether, which in alcohol with the calculated amount of fumaric acid in the fumarate is transferred, which is reprecipitated from alcohol-ether and in 3.9 g yield with mp. 132-133 ° C and = + 28.47 ° (c = 1, methanol) is obtained.
