WebAcetoin (AC) is an important platform bulk chemical with versatile applications. It exists in two stereoisomeric forms: (3R)-AC and (3S)-AC. Both stereoisomers could be potentially applied in the pharmaceutical industry, agriculture, and in optically active α-hydroxyketone derivative synthesis. Chiral AC production has recently become a new research focus in …
