By hydroboration of 10-undecen-1-ol acetate, a new synthetic route for the sex phero-mone of the Asian corn-borer (Ostrinia furnacalis Guenee) was devised to shorten the origi-nal 5 steps to a 2 steps reaction. The E- and Z-12-tetradecen-1-ol acetates were obtainedseparately with a purity greater than 98%. The location of the double bond position was as-certained by capillary GC and GC-MS. The important intermediate 12-tetradecyn-1-ol was also obtained from 2-tridecyn-1-ol byusing a zipper reaction, then by methylation and aeetylation. The intermediate obtainedfrom 3 different routes were compared by GC and GC-MS spectra to be identical.
