Application
(S)-(+)-1,2-Propanediol can be used as a reactant to synthesize:
- Optically active chiral (S)-1, 2-propanediol derivatives using mesogenic carboxylic acids via esterification in the presence of dimethylaminopyridine (DMAP) as a catalyst.
- 3,4-Ethylenedioxythiophenes via Mitsunobu reaction.
- Vicinal diol cyclic sulfates in the presence of sodium periodate and ruthenium chloride as catalysts.
