  Synthesis of (7Z,9Z)-dodecadienyi acetate, a component of sex pheromones of the leafrollersEpinotia andEucosma, using conjugated diynols

  摘要：

  Two analogous routes to the title pheromones were elaborated based on organocuprate cross-coupling of Z,Z-dienic electrophiles, (2Z,4Z)-1-acetoxy-2,4-heptadiene (6) and (3Z,5Z)-1-bromoctadiene (8), with omega-tert-butoxy-1-chloropentane and -butane, respectively. Optimal conditions for the reduction of 2,4-heptadiyn-1-ol and 3,5-octadiyn-1-ol to the respective Z,Z-alkadienols as precursors for the electrophiles were found. Treatment of diynols with activated zinc in aqueous alcohol provided high geometrical purity of the product (greater-than-or-equal-to 94 %). In both cases, copper-catalyzed cross-coupling afforded 1-tert-butoxy-7,9-dodecadiene (four stereoisomers), acetolysis of which gave the target pheromone contaminated by stereoisomers. In the case of allylic electrophile 6, the reaction occurred with the loss of the initial configurational purity, whereas the use of homoallylic bromide 8 ensured almost complete retention of the configuration of the double bonds and obtaining the target pheromone of 87 % configurational purity.

  According to one embodiment, an actinic-ray- or radiation-sensitive resin composition includes a resin containing a repeating unit (A) containing both a structural moiety (S1) that is decomposed by an action of an acid to thereby generate an alkali-soluble group and a structural moiety (S2) that is decomposed by an action of an alkali developer to thereby increase its rate of dissolution into the alkali developer, and a compound that generates an acid when exposed to actinic rays or radiation.
