    Transformation of carboxylic acid esters into 2-substituted allyl halides through tertiary cyclopropyl sulfonates. Application in the synthesis of (±)-ipsenol and (±)-ipsdienol, components of Ips typographus spark beetle pheromone
    摘要:
    Cyclopropanation of the ester group in ethyl 3-chloropropanoate and subsequent cleavage of the three-membered carbocycle in intermediate 1-(2-chloroethyl)cyclopropyl methanesulfonate gave 2-bromomethyl-4-chlorobut-1-ene, and the latter was used as key intermediate in the synthesis of racemic ipsenol and ipsdienol which are components of Ips typographus L. European spruce spark beetle pheromone.

    日期:——
    tertiary cyclopropanols are converted into 2-substituted allyl bromides in high yields under the action of magnesium bromide in diethyl ether. Magnesium chloride, aluminium chloride and titanium tetrachloride also induce effectively the transformation of cyclopropyl sulphonates into the corresponding allyl chlorides.
