    • The construction of the carbon carbon double bond (from 6 or 11 by Wittig reaction) will not be discussed in this preliminary report because it has been already done by us and others. For the trans series see our reference 1, for the cis series see our reference 7.

    • Reactions of 3-bromo or 3- iodo-pentane with triphenyl phosphine lead to mixtures of 3-pentyl triphenyl phosphonium salts and 2-pentyl triphenyl phosphonium salts. 3-pentyl triphenyi phosphonium iodide (F=190°) is prepared from 1-propyl triphenyi phosphonium iodide (nBuLi,THF) through the 1-propylidene triphenyl phosphorane which is in turn reacted with ethyl iodide (yield : 80%).
