Procedure

To lithium tri-sec-butylborohydride (2.7 mL of a 1.0 M solution in tetrahydrofuran, 0.0027 mol) cooled to -65~C. was added 3-(3-methoxy-3-methylbutyl)-5,5-dimethylcyclohexan-1-one (0.5 g, 0.0022 mol) dissolved in tetrahydrofuran (3.5 mL). The mixture was allowed to stir at 25~C. for 16 hours. Workup yielded 3-(3-methoxy-3-methylbut-1-yl)-5,5-dimethylcyclohexan-1-ol, bp1.0 210-212~C. (0.31 g). This compound was determined to possess a warm woody note.
