On December 21, 2000, Wagner, Alain; Mioskowski, Charles; Mohar, Barbara; Desmurs, Jean-roger; Le Guyader, Frederic; Schlama, Thierry published a patent.Application of 167316-28-1 The title of the patent was Sulfonamides and carboxamides and their use in asymmetrical catalysis. And the patent contained the following:
Optically active diamines were converted to their monosulfonamides with fluorinated alkane- or arenesulfonyl halides. The resulting sulfona,ides were used as ligands in the stereoselective reduction of ketones or in the stereoselective oxidation of racemic alcs. Thus, (1S,2S)-1,2-cyclohexanediamine was treated with F3CSO2Cl to give (1S,2S)-N-trifluoromethylsulfonyl-1,2-cyclohexanediamine (I). I was used together with [RuCl2(p-cymene)]2 to reduce PhCOMe to (S)-HOCHPhMe and to preferentially oxidize (S)-HOCHPhMe to PhCOMe, leaving enriched (R)-HOCHPhMe. The experimental process involved the reaction of N-[(1S,2S)-2-Amino-1,2-diphenylethyl]-1,1,1-trifluoromethanesulfonamide(cas: 167316-28-1).Application of 167316-28-1
