実験手順

To a suspension of lithium aluminum hydride (0.19 g, 5 mmol) in anhydrous ether (10 mL) was added 2-isopropylidene-7,9-dimethylspiro[4.5]decan-8-one (1.6 g, 7.3 mmol), prepared according to Example 23, in ether (3 mL) under nitrogen. The mixture was stirred at room temperature for 2 hours and then excess hydride decomposed by addition of wet ether. The solution was filtered, dried (Na2SO4) and concentrated on a rotary evaporator. Kugelrohr distillation gave 1.4 g, bp 150° C./0.5 mm, of the alcohol having the structure: ##STR36##
