Two stereocontrolled synthetic approaches to (E,E,E) and (Z,E,E)-α- chloro-ω-substituted hexatrienes 1-3 are described starting from unsaturated compounds 4-6. The key step of the first approach is based on the palladium- catalyzed rearrangement of bis-allylic acetates 4 and 5 and the second one is based on the stereoselective reduction of homopropargylic alcohols 6 followed by an elimination reaction. These stable chlorotrienes 1-3 are suitable synthetic intermediates for the construction of navenone B and all E polyenes (trienes, tetraenes, hexaenes and heptaenes).

Stereoselective reduction of conjugated homopropargylic alcohols 1 followed by an elimination reaction, allows an efficient approach to stereodefined (E,E,E)-chlorotrienes. The interest of these chlorotrienes was illustrated by a stereocontrolled synthesis of navenone B and all E conjugated polyenes (trienes, tetraenes and hexaenes).
