The present invention concerns a process for synthesis of 2,4,6-octatriene-1-oic acid and 2,4,6-octatriene-1-ol, which comprises the following stages:
a) reaction between 2,4-trans-hexadienal and triethyl phosphonoacetate to give ethyl 2,4,6-trans-octatrienoate;
b) alkaline hydrolysis of ethyl 2,4,6-trans-octatrienoate to give the corresponding alkaline salt;
c) acidification of said salt to give 2,4,6-trans-octatrienoic acid, which can be separated or can undergo the following further stages:
d) reaction of the 2,4,6-trans-octatrienoic acid with ethyl chloroformiate to give the mixed anhydride formed by 2,4,6-trans-octatrienoic acid and ethyl carbonic acid;
e) reduction of said mixed anhydride with sodium borohydride to give 2,4,6-transoctatrienol;
and optionally a purification stage of the end product.
