Aa. Vasil'Ev et al., Synthesis of (3S*,4R*,6E,10Z)-3,4,7,11-tetramethyltrideca-6,10-dienal (faranal) using stereospecific 1,4-cis-hydrogenation of conjugated double bonds, J CHEM S P1, (14), 2000, pp. 2211-2216
(+/-)-Faranal was synthesised by a convergent route involving 1,4-cis-hydro
genation of two properly substituted conjugated diene building blocks to in
troduce stereospecifically the 6(E) and 10(Z) double bonds of the final tar
get molecule. meso-2,3-Dimethylsuccinic acid was used to prepare a building
block for the 'right-hand' part of faranal carrying two vicinal erythro-co
nfigured methyl groups.
