Abstract
Abstract Sterospecific synthesis of an attractant for the codling moth by reacting sorbic aldehyde with an organo-metallic reagent to yield a 1-ether of trans-8-trans-10-dodecadiene-1,7-diol which is reduced via a 7-sulfonic acid ester to yield an ether of trans-8-trans-10-dodecadiene-1-ol and hydrolyzed to trans-8-trans-10-dodecadien-1-ol. ##SPC1##
