A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, Application In Synthesis of (S)-[1,1′-Binaphthalene]-2,2′-diol, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 18531-99-2, Name is (S)-[1,1′-Binaphthalene]-2,2′-diol, molecular formula is C20H14O2.

Improved resolution methods for (R,R)- and (S,S)-cyclohexane-1,2-diamine and (R)- and (S)-BINOL
Starting from inexpensive L-(+)-tartaric acid, it was possible to resolve and obtain pure both enantiomers of trans-cyclohexane-1,2-diamine 1 and thence both enantiomers of BINOL 2, two of the most powerful, chiral inducing backbones in asymmetric catalysis. The modified method is very economic, not only due to an almost doubling of the overall yields of enantiomerically pure compounds (86% 1, 83% 2) but also due to the easy recovery of resolving agent 1 [66% (R,R)-1, 79% (S,S)-1] in the BINOL resolution. An improvement in the yield of the preparation of racemic BINOL is also recorded.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 18531-99-2, help many people in the next few years.Application In Synthesis of (S)-[1,1′-Binaphthalene]-2,2′-diol
