  fruit-typical 2-alkyl esters by capillary gas chromatography using heptakis(2,3-di-O-methyl-6-O-tert-butyldimethylsilyl)-β-cyclodextrin as chiral stationary phase. An efficient method was developed to prepare the ester enantiomers via lipase-catalyzed esterifications: optically pure (R)-2-alkyl esters (ee > 99.9%) were obtained by esterification of the racemic alcohols with enantioselective Candida antarctica

• A green resolution–separation process for aliphatic secondary alcohols
  作者：Liwei Ren、Tian Xu、Ruoping He、Zhenhua Jiang、Hua Zhou、Ping Wei

  日期：2013.3

  In order to obtain both enantiomers of aliphatic secondary alcohols via a greener method, the four-step resolution-separation process involving lipase-catalyzed enantioselective esterification and hydrolysis as well as two separation procedures both via heterogeneous azeotropic distillation was developed. (S)-2-Pentanol (ee = 98.6%), (R)-2-pentanol (ee >99%), (S)-2-octanol (ee = 98.2%), and (R)-2-octanol (ee = 98.5%) were all produced in high purity (>98%) and high yield (>90%). In addition to the two model substrates, this method could also be applied to the resolution of other aliphatic secondary alcohols. (C) 2013 Elsevier Ltd. All rights reserved.
• Chiral esters: Sex pheromone of the bagworm,Oiketicus kirbyi (Lepidoptera: Psychidae)
  作者：Marc Rhainds、Gerhard Gries、Jianxiong Li、Regine Gries、Keith N. Slessor、Carlos M. Chinchilla、A. Cameron Oehlschlager

  DOI：10.1007/bf02033712

  Gas chromatographic-electroantennographic detection (GC-EAD) analyses of pheromone extract of female bagworms, Oiketicus kirbyi (Guilding), revealed five EAD-active compounds. Retention index calculations, GC-mass spectrometry in both full-scan and selected-ion monitoring modes and GC-EAD analyses of authentic standards identified the compounds as 1-methylbutyl octanoate (MBO), 1-methylbutyl nonanoate (MEN), 1-methylbutyl decanoate (MBD), 1-methylpentyl decanoate (MPD), and 1-methylbutyl dodecanoate (MBDD). Of these five chiral esters, MBD was most abundant in extracts and elicited the strongest antennal response. In field experiments in Costa Rica, (R)-MBD attracted O. kirbyi males, whereas (S)-MBD in combination with (R)-MBD inhibited response. R but not S enantiomers of MBO, MEN, and MBDD strongly synergized attraction to (R)-MBD. (S)-MBO and (S)-MBDD were inactive, whereas (S)-MBN was inhibitory. (R)-, (S)- and racemic MPD were inactive. Blends of (R)-MBD in ternary combination with either (R)-MBO and (R)-MBN or (R)-MBN and (R)-MBDD were as attractive as the five-ester blend. Five- and four-ester blends were equally attractive, suggesting redundancy of pheromone components for attraction of males. The multiple sex pheromone component blend of chiral esters in O. kirbyi may have evolved to maintain species-specific communication in bagworm communities of tropical Americas.
