Paragraph 0282; 0283, (2018/06/15)
There are provided methods of efficiently producing compounds that are, for example, sex pheromones of San Jose Scale. For example, there is provided a method for producing a 7-methyl-3-methylene-7-octenyl carboxylate compound (4), the method including the steps of: hydrolyzing a 7-methyl-3-methylene-7-octenal acetal compound (1) to obtain 7-methyl-3-methylene-7-octenal (2); reducing the 7-methyl-3-methylene-7-octenal (2) to obtain 7-methyl-3-methylene-7-octenol (3); and esterifying the 7-methyl-3-methylene-7-octenol (3) to obtain a 7-methyl-3-methylene-7-octenyl carboxylate compound (4).

Ketal ester 9 has been prepared in five steps from methyl levulinate 4 (scheme 1).The propionate 1, diol 2 and (+/-) frontalin 3 were prepared from ester 9 employing the routes shown in scheme 2,3 and 4 respectively.The branched chain alkenes 13 and 20 were prepared conveniently from the primary alcohols 11 and 10 following the procedure of S.Wolff.Triethyl phosphonopropionate 7 has been prepared by methylating triethylphosphonoacetate with methyl iodide in the presence of sodium hydride.

The utilisability of the isomerization of the terminal double bond in terpenic compounds with trifluoroacetic acid was investigated.The results obtained were used in the synthesis of the main part of the pheromone of Quadraspidiotus perniciosus COMSTOCK, i.e. (2E)-3,7-dimethyl-2,7-octadien-1-yl propionate.
