YoujiHuaxue 1991, 11(5), 530-3(Ch).The enantiomeric 14-methyl-1-octadecenes were prepd. by cross coupling reation between the Grignard reagent of 12-chloro-2-methylhexane from corresponding (R)-or (S)-2-methylhexanoic acid under the catalysis of Li2CuCl4. The overall yied of the each enantiomer is about 30% from the racemic 2-methylhexanoic acid and the optical purity is approx.100%. The (S)-enantiomer showed strong bioactivity as the sex pheromone of peach leafminer moth in field tests. |
