Starting with industrially available 1,3-dichloropropene a stereoselective process was developed for the preparation of (4E)-tridec-4-en-1-yl acetate, sex pheromone of tomato pinworm (Keiferia lycopersicella) using in the key stage the Fe-catalyzed cross-coupling of ethyl (4E)-5-chloropent-4-enoate with octylmagnesium bromide.
Preparation of alkenols
-
, (2008/06/13)
A process for preparing alkenols of the formula I where R1 is hydrogen or a hydrocarbon radical, and n is an integer from 3 to 15, a) by reacting a phosphonium salt of the formula IIa where X is chlorine, bromine or iodine, with an aldehyde of the formula IIIa or its hemiacetal of the formula IIIb STR1 or b) by reacting a phosphonium salt of the formula IIb with a aldehyde of the formula IV in a solvent in the presence of a base, wherein the base is the alkali metal salt of an alcohol and the solvent is an alcohol.

Interaction of deprotonated acetylcyclopropane cyclohexylimine with several aliphatic alkyl halides, epoxides, and aldehydes efficiently gave the corresponding cyclopropyl ketones.Some of the respectible alcohols were rearranged in a highly stereoselective manner under the action of trimethylsilyl bromide in the presence of zinc bromide into the corresponding linear (E)-homoallyl bromides.The latter were used, in turn, as key intermediates in concise syntheses of thirteen terminally functionalized straight-chain oligoolefins which are known to constitute acetogenin pheromonal components for more than 65 species of lepidopteran insects.
