In an article, author is Wang, Xiaonan, once mentioned the application of 146439-94-3, Safety of H-SER-ILE-LYS-VAL-ALA-VAL-OH, Name is H-SER-ILE-LYS-VAL-ALA-VAL-OH, molecular formula is C8H9FO, molecular weight is 615.76, MDL number is N/A, category is chiral-catalyst. Now introduce a scientific discovery about this category.
An efficient enantioselective addition of thiols to acyclic trifluoromethyl ketimines has been established by using a bifunctional squaramide catalyst, which was derived from quinine, and the reaction was completed in 5 to 10 min. The construction of chiral tetrasubstituted carbon centers bearing trifluoromethylatedN,S-ketals has been achieved in high yields (up to 96% yield) with excellent enantioselectivities (up to 99% ee).
If you are interested in 146439-94-3, you can contact me at any time and look forward to more communication. Safety of H-SER-ILE-LYS-VAL-ALA-VAL-OH.
