- Asymmetric synthesis of deoxypolypropionate units via stereoselective hydrogenation of optically active cycloheptatriene.
Asymmetric synthesis of deoxypolypropionate units via stereoselective hydrogenation of optically active cycloheptatriene.
Optically active polypropionate units were synthesized in 9-11 steps from 3,5-dimethylphenol. The sequence consists of the Buchner reaction controlled by a chiral 2,4-pentanediol tether and diastereoselective hydrogenation over Raney nickel. [reaction: see text]
