Efficient synthesis of 3E,13Z-octadecadienol, its acetate, 4E,6E,11Z-hexadecatrienal, and 4E,6E,11Z-hexadecatrienyl acetate, sex pheromones of some lepidopteran species
摘要:
The title linear acetogenins have been synthesized by a strategy of joining acetylcyclopropane to 8Z-tridecenol or 5Z-decenol prepared after Julia, leading to the corresponding secondary cyclopropylcarbinols. The ZnBr2/Me3SiBr-initiated homoallylic rearrangement of the latter assures at a key step the stereospecific construction of transoid fragments of the target molecules.
