Pheromone synthesis. Part 243: Synthesis and biological evaluation of (3R,13R,1′S)-1′-ethyl-2′-methylpropyl 3,13-dimethylpentadecanoate, the major component of the sex pheromone of Paulownia bagworm, Clania variegata, and its stereoisomers

All of the four stereoisomers of (1′S)-1′-ethyl-2′-methylpropyl 3,13-dimethylpentadecanoate, the major component of the female sex pheromone of Clania variegata, were synthesized by employing olefin cross metathesis as the key reaction and starting from (R)- or (S)-2-methyl-1-butanol, (R)- or (S)-citronellal, and (S)-2-methyl-3-pentanol. Their bioassay revealed the (3R,13R,1′S)-isomer as the bioactive one, whose more efficient synthesis was achieved in two different ways by employing Wittig reaction as the key step.

Synthesis of all the four stereoisomers of (1′S)-1-ethyl-2-methylpropyl 3,13-dimethylpentadecanoate, the major component of the sex pheromone of Paulownia bagworm, Clania variegata

All the four stereoisomers of (1′S)-1-ethyl-2-methylpropyl 3,13-dimethylpentadecanoate, the major component of the sex pheromone of Clania variegata, were synthesized by starting from (R)- or (S)-2-methylbutan-1-ol, (R)- or (S)-citronellal, and (S)-2-methylpentan-3-ol. Olefin cross metathesis was employed as the key reaction.

Synthesis of Chiral Alcohol and Ester Pheromones through Enzyme-Catalysed Hydrolysis using Pseudomonas fluorescens Lipase: Preparation of (2R,6S,10S)-6,10,14-Trimethylpentadecan-2-ol and the Propionate of (2R,8R)-8-Methyldecan-2-ol

(2R,6S,10S)-6,10,14-Trimethylpentadecan-2-ol , one of the stereoisomers of the sex pheromone of Corcyra cephalonica Stainton, was synthesized in highly optically pure form by the hydrolysis of the 2,2,2-trichloroethyl carbonate of (2RS,6S,
