Citronellal → (-)-Isopulegol

참여 물질

반응 단계

The aluminium siloxide (Ia) or (Ib) was prepared analogously to Example 4 in 5 ml Marlotherm S® (isomer mixture of isomeric dibenzyltoluenes). 200 mmol citronellal were then added at room temperature to a solution containing 2 mmol of freshly prepared aluminium siloxide over a period of 15 min. When the metering in had ended, the reaction mixture was stirred at room temperature for a further 2 h and the reaction was then interrupted by addition of 50 ml 15% strength sodium hydroxide solution. After washing neutral and distilling off the solvent, the reaction product B2 was obtained as a colourless oil, yield: 14.8 g.
