Research paper thumbnail of Total synthesis of (R)-lipoic acid and (S)-lipoic acid via an Mn (III)-salen-catalyzed oxidative kinetic resolution

Tetrahedron: Asymmetry, 2015

The asymmetric synthesis of both the antipodes of a-lipoic acid is described. The total synthesis... more The asymmetric synthesis of both the antipodes of a-lipoic acid is described. The total synthesis of racemic and asymmetric lipoic acid is achieved from propane 1,3-diol. This work reports the use of Mn (III)-salen-catalyzed oxidative kinetic resolution as the key step to obtain enantiomerically pure (R)-and (S)-lipoic acid. The undesired product formed during the resolution can be recycled to achieve the desired isomer.
