137848-28-3, (R)-2′-amino-[1,1′-binaphthalen]-2-ol is a chiral-catalyst compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
General procedure: This compound was prepared as a yellow solid from the reaction of pyridine-2-carboxaldehyde (1.07 g, 10.0 mmol) with (R)-2-amino-2′-hydroxy-1,1′-binaphthyl (2.85 g, 10.0 mmol) indry toluene (50 mL) in the presence of 4 A molecular sieves at 70 C and recrystallization from a toluene solution by a similar procedure as in the synthesis of 1H2. Yield: 2.99 g (80%). M.p.: 180-182 C. 1H NMR (C6D6): d 8.62 (s, 1H, CHN), 7.88 (s, 1H, aryl), 7.61 (m, 2H, aryl), 7.52 (m, 5H, aryl), 7.24 (d, J = 8.0 Hz, 1H, aryl), 7.10-6.95 (m, 5H, aryl), 6.56 (t, J = 6.8 Hz, 1H, aryl), 6.24 (m, 1H,aryl); the proton of the OH group was not observed. These spectroscopic data were in agreement with those reported in the literature [69].
