Synthesis of Dienic Pheromones of Codling Moth and Grape Vine Moth
The synthesis of pheromones 8E,10E-dodecadien-1-ol (I) and 7E,9Z-dodecadien-1-yl acetate (II) via sulphone intermediates has been accomplished.The α-anions of the sulphones (2) and (10) on reaction with the aldehydes (5) and (11) followed by acetylation of the resulting products in situ afford the β-acetoxysulphones (6) and (12) respectively.Reductive elimination of 6 and 12 with Na/Hg provide the dienic compounds, which on depyranylation and acetolysis yield I and II respectively.
