In an article, published in an article, once mentioned the application of 23190-16-1, Name is (1R,2S)-(−)-2-Amino-1,2-diphenylethanol,molecular formula is C6H5CH(NH2)CH(C6H5)OH, is a conventional compound. this article was the specific content is as follows.Quality Control of: (1R,2S)-(−)-2-Amino-1,2-diphenylethanol
The preparation of several C2-symmetric disulfonamides derived from 1,2-amino alcohols and disulfonyl derivatives, as well as their use in the titanium tetraisopropoxide-promoted enantioselective additions of dialkylzinc to aldehydes are described. The enantiomeric ratio is up to 96:4, the best results being obtained for aromatic aldehydes with electron-donating groups in the para-position. There are some differences in the enantioselectivity depending on the relative positioning of the amino alcohol moieties in the chiral ligand, the 1,3-disulfonyl derivative being the best system. In the case of para-substituted benzaldehyde derivatives, a negative relationship between the electron-withdrawing character of the para-substituted group and the enantioselectivity of the addition was seen, whereas the more electronic-donating character the substituent has, the higher the observed enantioselectivity.
