Abstract
Pine sawflies of the genera Neodiprion, Diprion and Gilpinia (Diprionidae) are malignant and economically important pests of coniferous trees. The most effective and environmentally safe method of controlling and regulating the number of pine sawflies is the use in traps of synthetically obtained sex feromone, identified for its different species as acetates and propionates of 3,7-dimethyl-2-pentadecan-2-ol (diprionol) in the form of various stereoisomeric forms due to the presence of three asymmetric carbon atoms. At the same time, it was noted that the 2S configuration of the optical centre of the erythro-isomerium is crucial for the stereochemistry of the sex pheromone of pine sawflies. The article presents the results of research of the laboratory of insect bioregulators of the Ufa Institute of chemistry of the UFIC RAS in the field of synthesis of optically active pine Sawfly pheromone, its stereoisomers and analogues based on (S)-(+)-dihydromircene and (-)-mentolactone obtained from available natural monoterpenes – (+)-α-pinene and l-menthol, respectively.
