WebMay 14, 2024 · Although many chiral ligands for asymmetric catalysis have been developed, there is still a need for new structures allowing the modular approach. Recently, easy synthesis of chiral pyridine-containing β-amino alcohols has been elaborated by opening respective epoxides with enantiomeric 1-phenylethylamine. This paper reports the … 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 …
