SYNTHESIS OF THE PHEROMONES, (E)-3,7-DIMETHYL-2,7-OCTADIENYL PROPIONATE, (E)-3,7-DIMETHYL-2-OCTENE-1,8-DIOL AND FRONTALIN FROM A COMMON INTERMEDIATE

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.
