Synthesis of ocimin, a 1,5-diene, by a bis-Grignard reaction
Ocimin, 1,6-bis-(4-methoxyphenyl)-(E)-(E)-hexa-1,5-diene, was synthetized by the bis-Grignard reaction of p-anisaldehyde with 1,4-bis- (bromomagnesium)butane and the dehydration of the intermediate diol using triphenylphosphine-carbon tetrachloride.

Synthesis of Ocimin, a Neolignan from Ocimum americanum Linn.
Ocimin (I), a neolignan isolated from Ocimum americanum Linn. has been synthesized for the first time starting from 1,6-di-(p-methoxyphenyl)-1,6-hexanedione (II).Sodium borohydride reduction of II in dioxane-ethanol gives the corresponding diol (III) whic
