Pheromone synthesis. Part 258. Synthesis of the enantiomers of the beetle pheromones ethyl 4-methylheptanoate, 4-methyloctanoic acid and 4-methyl-1-nonanol, and HPLC analysis of their derivatives to determine their enantiomeric purities

The enantiomers of citronellal have been converted into the enantiomers of the following beetle pheromones: ethyl 4-methylheptanoate (produced by male Nicrophorus vespilloides), 4-methyloctanoic acid (produced by male Oryctes elegans), and 4-methyl-1-nonanol (produced by female Tenebrio molitor). The enantiomeric purities of the synthetic pheromones were determined by HPLC analysis of the corresponding acids after derivatization with Ohrui's reagent [(S)-1-(anthracene-2,3-dicarboximido)-2-propanol]. The enantiomers of 4-methyl-1-nonanol could also be analyzed employing another Ohrui's reagent [(1S,2S)-2-(naphthalene-2,3-dicarboximido)cyclohexane-1-carboxylic acid].

Asymmetric synthesis of (R)- and (S)-4-methyloctanoic acids. A new route to chiral fatty acids with remote stereocenters

The enantioselective synthesis of both enantiomers of 4-methyloctanoic acid, one major aggregation pheromone component of the rhinoceros beetles of the genus Oryctes and an important aroma compound, is described. The key step of the synthesis is based on

METHODS FOR USING AMINO ACIDS WITH AFFINITY FOR THE ALPHA-2-DELTA PROTEIN

This invention relates to certain ?-amino acids that bind to the alpha-2-delta ((x2S) subunit of a calcium channel. These compounds and their pharmaceutically acceptable salts are useful in the treatment of a variety of psychiatric, pain and other disorders.
