A short synthetic sequence for the preparation of methyl (6S)-(-)-6,8-dihydroxyoctanoate, the precursor to (R)-(+)-α-lipoic acid is described starting from (2S)-(+)-2-(tetrahydro-2-furyl)ethanol.
The synthesis of methyl (S)-(-)-6,8-dihydroxyoctanoate as a precursor of (R)-(+)-α-lipoic acid was accomplished by using methyl (S)-(-)-(2-oxocyclohexyl)acetate, which had been obtained from baker’s yeast reduction, as a chiral starting material.
