Participants

Reaction Steps

To 5 ml of an anhydrous THF suspension containing 274 mg of lithium aluminum hydride was slowly added 10 ml of an anhydrous THF solution containing 1.0 g of 1-(1,2-dihydroxy-2,6,6-trimethylcyclohexyl)oct-1-yn-3-ol under ice-cooling in a nitrogen atmosphere. After the addition, the mixture was placed under refluxing conditions and stirred for 10 hours. After completion of the reaction, the reaction mixture was cooled, and 0.3 ml of water, 0.3 ml of a 15% sodium hydroxide aqueous solution, and 1.0 ml of water were carefully added thereto in this order, followed by vigorously stirring for 20 minutes. Any insoluble matter was removed by filtration with suction, and the filtrate was concentrated under reduced pressure. The resulting solid was purified by silica gel column chromatography to obtain 568 mg (yield: 60%) of 1-(2-hydroxy-2,6,6-trimethylcyclohexylidene)oct-1-en-3-ol.
