(8S,9S,10R,13S,14S)-10,13-dimethyl-1,2,6,7,8,9,11,12,14,15,16,17-dodecahydrocyclopenta[a]phenanthren-3-one

反応条件: temp:3.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 4-Androstene-3-one (4.3g) is dissolved in 300ml of methanol and cooled to 3° C in an ice-water bath. To the cooled mixture is added 20ml of 30% hydrogen peroxide and 26ml of 4N sodium hydroxide solution simultaneously from 2 dropping funnels. The addition is carried out in a nitrogen atmosphere with stirring. The mixture is allowed to warm to room temperature and stirring is continued for an additional hour. The mixture is diluted with 4 liters of water and extracted with methylene chloride. The organic layer is dried over sodium sulfate and concentrated to yield 3.0g of the title compound. The addition to warm to room temperature stirring is continued for an additional hour extracted with methylene chloride The organic layer is dried over sodium sulfate concentrated
