Synthesis of new mono-N-tosylated diamine ligands based on (R)-(+)-limonene and their application in asymmetric transfer hydrogenation of ketones and imines was written by Roszkowski, Piotr;Maurin, Jan K.;Czarnocki, Zbigniew. And the article was included in Tetrahedron: Asymmetry in 2013.HPLC of Formula: 120121-01-9 This article mentions the following:
A synthetic procedure leading to the preparation of a new family of enantiopure mono-N-tosylated-1,2-diamines derived from (R)-(+)-limonene is described. (+)-Limonene was transformed into the appropriate N-tosyl derivative using N-tosylaziridination based on chloramine-T trihydrate. Subsequent ring opening by sodium azide afforded the corresponding isomeric azides. Finally, reduction of the azide function gave enantiomerically pure mono-N-tosylated-1,2-diamines. The ligands obtained proved to be effective in the asym. transfer hydrogenation protocol on aromatic ketones and imines. In the experiment, the researchers used many compounds, for example, (R)-1-(3-Chlorophenyl)ethanol (cas: 120121-01-9HPLC of Formula: 120121-01-9).
(R)-1-(3-Chlorophenyl)ethanol (cas: 120121-01-9) belongs to alcohols. Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. Tertiary alcohols cannot be oxidized at all without breaking carbon-carbon bonds, whereas primary alcohols can be oxidized to aldehydes or further oxidized to carboxylic acids.HPLC of Formula: 120121-01-9
