L-孟醇与过量外消旋菊酰氯反应表现出非对映异构体选择性 ,得到了光学活性菊酸的L -孟醇酯。由外消旋菊酸的 L -孟醇酯经异构化反应也得到了光学活性菊酸的 L -孟醇酯。
Reaction of L-menthyl alcohol with excess racemic chrysanthemic acid chloride showed diastereoselectivity, yielding L-menthyl alcohol optically active chrysanthemic acid. The L - menthyl alcohol ester of optically active chrysanthemic acid was also obtained from isomerization reaction of racemic chrysanthemic acid L - menthyl alcohol ester.
