Dibenz[b,f]oxepin-10(11H)-one

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Reflux of 25 ml of 2-fluoro-11-[β-(dimethylamino)-ethoxy]dibenz[b,f]oxepin stock solution produced no apparent decomposition after 45 minutes. Addition of 2.5 ml of concentrated hydrochloric acid and further reflux for 10 mins gave complete decomposition to 10,11-dihydro-10-oxodibenz[b,f]oxepin. produced no apparent decomposition after 45 minutes further reflux for 10 mins

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a solution of 42 g of the compound 10-keto-10,11-dihydrodibenzo(b,f)-oxepine in 200 ml of dry ethanol a solution of sodiumethoxide (7 g of sodium in 500 ml of ethanol) is added dropwise. After stirring the mixture for 30 minutes 16.2 ml of methylvinylketon in 50 ml of ethanol are added, whereupon the solution is refluxed for 1 hour. The solution is cooled then and poured into 2 N HCl. After extracting into ether, washing the ether layer with water (till neutral) and drying the etherial phase, the solvent is evaporated. are added, whereupon the solution is refluxed for 1 hour The solution is cooled After extracting into ether washing the ether layer with water (till neutral) drying the etherial phase the solvent is evaporated
