The fourstereoisomers of 7-acetoxy-15-methylnonacosane (1), a component of the femalesexpheromone of the New World screwworm fly (Cochliomyia hominivorax) were synthesized. The stereogenic center at C-15 of 1 originated from that of the enantiomers of citronellal, and that at C-7 was generated by lipase-catalyzed asymmetric acetylation of (3RS,11R)- and (3RS,11S)-17-methyl-1-trimethylsilylpentacos-1-yn-3-ol

The enantiomers of 3-methylpentacosane, 3-methylheptacosane, 3-methylnonacosane, 13-methylheptacosane, and 5-methylheptacosane were synthesized by starting from the enantiomers of 2-methylbutyl bromide or citronellol. These methyl-branched alkanes are the characteristic components of the cuticular hydrocarbons of queen of the ant, Diacamma sp.
