Stereospecific synthesis of transoid mono- and 1,3-diene pheromones ofLepidoptera from secondary cyclopropylcarbinols
摘要:
The zinc halide-initiated homoallylic rearrangement of saturated or allylic cyclopropylcarbinols in the presence of trimethylsilyl halides has been employed as the key step in the total synthesis of seven behavioral regulators in twenty insects of the Lepidoptera family, namely 9E-tetradecenol and its acetate, 11E-hexadecenol and its acetate, 11E-hexadecenal, 5E, 7E-dodecadienol, and 3E,5E-tetradecadienyl acetate.
