High Quality Content by WIKIPEDIA articles! NOBIN (2-amino-2`-hydroxy-1,1`-binaphthyl) is an organic molecule used for asymmetric catalysis. NOBIN is related to BINOL and other analogs by both having a chiral axis and being a scaffold for certain chemical reactions. NOBIN is an excellent catalyst for the aldol reaction producing reliable products, good yields, and excellent diastereoselectivity.
