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

实验步骤: To a suspension of 4.0 g. (13.7 mmole) of 2,2'-bipyridinium chlorochromate in 15 ml of dichloromethane is added, while stirring, 0.5 g. (3.5 mmole) of 2-isopropylcyclohexanol in 10 ml of dichloromethane. The resulting reaction mixture is stirred for 4 hours and then filtered through a Hirsch funnel packed with 2 cm of Celite®. The resulting clear filtrate is washed with 5% hydrochloric acid and 10% sodium carbonate, and dried over magnesium sulfate. The drying agent is then removed and the solvent evaporated to yield a colorless oil which is distilled via Kugelrohr to yield pure 2-isopropylcyclohexanone in a typical yield of 0.425 g. which is 86% of theoretical yield. To a suspension of 4.0 g The resulting reaction mixture is stirred for 4 hours filtered through a Hirsch funnel The resulting clear filtrate is washed with 5% hydrochloric acid and 10% sodium carbonate dried over magnesium sulfate The drying agent is then removed the solvent evaporated to yield a colorless oil which is distilled via Kugelrohr

实验步骤: The synthesis was carried out in the same manner as described in Example 1, except that 20.0 g (0.141 mol) of 2-isopropylcyclohexanol (cis:trans=6:4) and 10.1 g (0.141 mol) of 1,2-butyleneoxide were used instead of 30.0 g (0.192 mol) of 2-tert-butylcyclohexanol (cis:trans=8:2) and 11.1 g (0.192 mol) of propyleneoxide. 6.5 g of 2-isopropylcyclohexanol and 16.6 g of 1-(2-isopropylcyclohexyloxy)-2-butanol (cis:trans=6:4) were obtained in a 55% yield.

实验步骤: 75.6 g (0.56 mol) of para-tolylisocyanate were placed with 500 ml toluene in a one litre vessel and subsequently 73.4 g (0.51 mol) of 2-isopropylcyclohexanol were added. The reaction mixture was heated to reflux for 6 hours. After cooling to room temperature 50 g of water were added and the mixture was refluxed for one more hour. After phase separation the solvent was stripped off and the crude product recrystallized from 235 g of n-heptane. The product (79.8 g) was obtained in form of off-white crystals in 99.2% purity. This corresponds to a theoretical yield of 56%. The reaction mixture was heated to reflux for 6 hours were added the mixture was refluxed for one more hour After phase separation the solvent the crude product recrystallized from 235 g of n-heptane
