undecan-5-one

反応条件: temp:55.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a suspension of 3 grams (18 mmol) of 2-adamantanone oxime in 36 ml of 20% aqueous sodium hydroxide were added 5 grams (28 mmol) of benzenesulfonyl chloride with vigorous stirring at a temperature of 20°-30° C. The temperature was maintained below 30° C. until the exothermic reaction ceased, then raised to 55° C. and held there for 2 hours. The reaction mixture was worked up leaving 2 grams of 4-azatricyclo[4.3.1.13,8 ]undecan-5-one as white crystals melting at 306°-308° C. (recrystallized from hexane). The temperature was maintained below 30° C. until the exothermic reaction The reaction mixture was worked up leaving 2 grams of 4-azatricyclo[4.3.1.13,8 ]undecan-5-one as white crystals melting at 306°-308° C. (recrystallized from hexane)

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: With 6.3 g of 8-amino-1-naphthol and 20 ml of ethanol, 8.1 g of 5-undecanone was mixed. The mixture was refluxed for 3 hours. The reaction mixture was condensed, and purified in a column chromatography (silica gel, n-hexane/ethyl acetate=1/6) to obtain 2.6 g of naphthooxazinine. The mixture was refluxed for 3 hours condensed purified in a column chromatography (silica gel, n-hexane/ethyl acetate=1/6)
