137848-29-4, (S)-2′-Amino-[1,1′-binaphthalen]-2-ol is a catalyst-ligand compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
A mixture of 0.100 g (0.351 mmol) of (S)-NOBIN and 0.115 g (0.422 mmol) of 2-benz[a]anthraldehyde-1-ol were refluxed in absolute ethanol (10 mL) under argon for 10 h producing a dark redsolution and precipitate. The mixture was hot-filtered and washed with hot ethanol to produce a dark red solid that was dried in vacuo. Yield of (S)-2: 0.591 g, 81% from (S)-NOBIN.
