摘要

(3Z, 2S)-7, 7-Ethylenedioxyhex-3-en-2-yl N-phenylcarbamate 7 gave the allylsilane 8,(2E, 4S)-7, 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 ...
