In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Kinetic Resolution of Racemic 3,4-Disubstituted 1,4,5,6-Tetrahydropyridine and 3,4-Disubstituted 1,4- Dihydropyridines via Rh-Catalyzed Asymmetric Hydrogenation, published in 2020-02-21, which mentions a compound: 36620-11-8, mainly applied to piperidine tetrahydropyridine preparation; tetrahydropyridine dihydropyridine asym hydrogenation rhodium catalyst, COA of Formula: C14H8BF4Rh.
Kinetic resolution of racemic 3,4-disubstituted 1,4,5,6-tetrahydropyridines and 3,4-disubstituted 1,4-dihydropyridines was developed by Rh-catalyzed asym. hydrogenation, affording chiral 3,4-disubstituted piperidines and chiral 3,4-disubstituted 1,4,5,6-tetrahydropyridines with high selectivity factors (s = up to 1057). Remarkably, all four stereoisomers of 3,4-disubstituted piperidine can be easily prepared using this method. Furthermore, the synthetic utility of this methodol. was demonstrated by efficient synthesis of antidepressant drug (-)-paroxetine.
As far as I know, this compound(36620-11-8)COA of Formula: C14H8BF4Rh can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
