    • [14] Standard procedure: 1 ml of a solution of 100 mM 4 in octane (unless indicated otherwise) containing 500 mM n-butanol and 45 mM hexadecane (internal standard) was mixed with enzyme and shaken at 45°C (unless indicated otherwise) and 250 rpm. The reaction was monitored by GC. Blanks showed no reaction.

    • [17] Typical procedure: 6 ml of a solution of 100 mM 4b and 500 mM n-butanol in toluene was added to 100 mg Candida rugosa lipase. After 2 h of magnetic stirring at 0°C (conversion = 52%), the solution was filtered, concentrated and chromatographed to give 5.1 mg linalool [18] (c.e. = 68%;, detd. by GC).
