Hydrogenation of terminal β-acetylene alcohols with lithium aluminum hydride in THF has afforded homoallylic alcohols. Decomposition of the intermediate organoaluminum complex with deuterated water, iodine, or pyridinium dibromide has evidenced abou

Methods have been developed for the synthesis of (2E)-1,1-dimethoxyalk-2-en-4-ols and (2E)-4-hydroxyalk-2-enals by reaction of (2E)-4,4-dimethoxybut-2-enals and Grignard compounds. Thermal isomerization of (2E)-4-hydroxyalk-2-enals gave the correspon

A new synthetic route to 1,3,5-undecatrienes and fucoserratene

Autor: O. A. Garibyan, G. M. Makaryan, A. L. Ovanesyan, Zh. A. Chobanyan

Publikováno v: Russian Journal of Applied Chemistry. 81:455-458

A new procedure for preparing natural alkatrienes, fucoserratene and 1,3,5-undecatrienes, was developed. The key step of both syntheses is stereoselective formation of double bonds by the Wittig reaction starting from (E)-4,4-dimethoxy-2-butenal.
