Pheromone synthesis. Part 265: Synthesis and stereochemical composition of two pheromonal compounds of the female Korean apricot wasp, Eurytoma maslovskii

摘要

2,10-Dimethyldodecyl propanoate and 2,8-dimethyldecyl propanoate are two pheromonal compounds secreted by the female Korean apricot wasp, Eurytoma maslovskii. The enantioselective synthesis of all the stereoisomers of both components was conducted; HPLC analysis based on the chiral derivatization method (Ohrui-Akasaka method) was applied for the clarification of the stereochemical composition of these two components. The most pheromonally active compound, (2S,10R)-dimethyldodecyl propanoate, was also the most abundant component in the cuticular extract. (C) 2020 Elsevier Ltd. All rights reserved.
