You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.23190-16-1, Name is (1R,2S)-(?)-2-Amino-1,2-diphenylethanol, molecular formula is C6H5CH(NH2)CH(C6H5)OH. In a patent, introducing its new discovery.
Asymmetric synthesis XVII. New chiral catalysts for the stereocontrolled addition of benzaldehyde by diethylzinc
Enantioselective addition of benzaldehyde with diethylzinc catalyzed by a few classes of new chiral ligands (3a-3h) and their structural relations are disclosed herein. The stereocontrolled syntheses of both (S)- and (R)-1-phenyl-1-propanol are achieved in high chemical yield (up to 99.3%) with high enantiomeric excess (up to 96.8% e.e) utilizing (1S,2R)-(3a) and (1R,2S)-2-N,N-dimethylamino-1,2-diphenyl ethanol (3b), respectively.
