Ph. Dussault et al., Application of the Sonogashira coupling reaction to the stereoselective synthesis of chiral 1,3-dienol ethers, SYNLETT, (12), 1998, pp. 1387-1389
Sonogashira couplings of 2-iodo enol ethers or ynol ethers provide enynes w
hich undergo semihydrogenation to afford 4-alkyl-1,3-dienol ethers. (IZ, 3E
), (IE, 3Z) and (1Z, 3Z)-4-alkyl-1,3-dienol ethers are accessible using thi
s strategy.
