7-ethylenedioxy-4-dimethyl(phenyl)silylhept-2-ene, introducing one stereogenic centre carrying a silyl group. Hydroboration–oxidation gave (2S,4S)-7,7-ethylenedioxy-4-dimethyl(phenyl)silylheptan-2-ol 9, controlling a second stereogenic centre. Conjugate addition of the phenyldimethylsilylcuprate reagent to the α,β-unsaturated imide (2′E,6′S,8′R,5S)-1-[8′-benzyloxy-6′-dimethyl(phenyl)silylnon-2′-enoyl]-5-tr
