Abstract The sex attractant of Scrobipalpuloides absoluta females is a 90: 10 mixture of (3 E, 8 Z, 11 Z)-3, 8, 11-tetradecatrien-1-yl acetate and (3 E, 8 Z)-3, 8-tetradecadien-1-yl acetate. Tetradecadienyl acetates bearing 8 Z, 11 Z; 3 E, 8 Z; and 3 E, 11 Z double bonds were synthesized by stereospecific procedures; the mass spectral and gas chromatographic properties of the 3 E, 8 Z isomer were found to be congruent with those of the ...
